to accurately show "ural" continent [asia] based on true length

.
MISSION OBJECTIVE: to accurately show "ural" continent [asia] based on true length
the southern part of "ural" extends westwardly beyond the ural mountains, [at "60 degrees east"] by around 30 degrees of circular planet, continuing and extending further west, until the Mediterranean sea.
a preferable method to teach would use a map marking a vertical line extending due-north from a point near cairo to saint petersburg [as the west edge of this one map], mostly because cairo is near the continental joint and also considering cairo 30n 31e similar to s.p. 60n 30e almost due north. we may measure the distance of southern "ural" basically 5300 miles, from "cairo to new-delhi to near-shanghai" because cairo is near the continental joint and aligns due south of baltic sea coast.
total length of southern "ural" is around 5300 miles. [calculated in km as: c.>n. 4400 kilometer+4200km from n>to coast of pacific ocean=around 8600 km=5300 miles]. this distance will be the length needed to make an accurate map which will accurately display distances in the northern areas of this continent.
we can also define the units of "squeezing" as 9 units, each unit 590 miles represented by HALF-INCH each unit [to practically and pragmatically fit in a study textbook 4.5 inches for map] from cairo to coast not including ocean which is important at the defining length for teaching the length of the northern part.
these units will define more accurately how many units from "Saint Petersberg" to "Sea of Okhotsk" to Kamchatka Peninsula.
2. the next row across "ural" can be measured: 5300 miles from a "point near istanbul" to tashkent to coast. [the vertical line does "leave out some of turkiye yet still most of that country is included and allows objectively using cairo and saint petersbeg] measuring units: tu.>ta.>pacific, because istanbul is 29e not due north of cairo 31e, so from a point near it, to ta. is 3200 km. to match the length mentioned we must extend to a total 8600 kilometer. 8600-3200=5400 km length to coast of pacific ocean. in fact including korean peninsula totals only 5100 miles as 8200 km is less than 8600 km. this row must include around 200 miles of water beyond korean peninsula to match the length.
FIRST SURPRISE OF CORRECTION
traveling from hong kong or shanghai to korean peninsula must move north and east and yet this peninsula is around 200 miles nearer to the west edge of 30 degrees line,  based on length, in contrast to length further south from joint to coast.
to teach this, the map must "curve" the land of "ural" continent [asia] so korean peninsula is nearer to turkey as well as including 400 km more water eastward to show "equal length" and this will also include some of "Kyushu" island part of "Nihon" [japan] because 8600-8200=400km. this demonstrates the length more visibly.
****ONLY in such a map is the "key" of "scaling per miles" accurate.
3. next row nearer "the top of the ball" similar to picture at https://pixabay .com/en/basketball-ball-game-recreation-155997/ we see the ball has vertical line representing line due north from point near continental joint to baltic edge, where the length around is less distance.
from 30 degrees east=30d.e., in western part of black sea to coast is 4970 miles or 8.4 units so less than the 9 units to the southern coast.
[calculated around 1200 miles of water from black sea to east edge of caspian sea and continuing to quadro-border of china-kazak.-mong.-russia=CKMR, totals length 4200 km +3800 km more to pacific coast totals 8000 km which is less than 8600km. 4200+3800=8000 kilometers. EQUAL length from 30 d.e. includes 600 km of water with Hokkaido island of "nihon" [japan]. the north part of japan aligns with the north part of black sea and this should be visible in one map.
to demonstrate the difference near the north: two helicopters travelling the same speed 99 kilometers per hour from 30 degrees east one starting near cairo and the other at point in western black sea, due north of cairo. the northern one will reach the coast sooner because less length same as traveling along the "top" of a basket-ball. by the time the southern craft reaches the coast, the northern will have moved the same distance and reach BEYOND Hokkaido island at the same speed and same time because same distance. the map should show this.
"Nihon" [japan] should be shown like true length nearer to black sea.because north japan aligns with crimea peninsula and in fact northern honshu at 40 degrees north, is truly more southward than the south edge of black sea and one map should show that.
i recommend improving accuracy because these improvement will more accurately describe this continent and we can proceed further north.
4. next row from saint peterburg at 60 degrees north and for this purpose "30 degrees east aligned due north from cairo," the map should show equal length. 5300 MILES [8600 km].
the west edge is baltic sea and from 30d.e. location of s.p. to coast is length 4600 miles far less than 5300 miles.
calculated length: 3100km from s.p. to place due north of quadro-border [c-k-m-r]+3000 km to coast named Sea of Okhotsk=6100 km far less than land in southern "ural". a difference of 2500 km less than 8600. even including the EAST coast of kamchatka peninsula is not enough length "only" [the huge] 4200 km totaling 7300 km. to fill in the length at this point north we must measure 5500 km from point mentioned [8600-3100] which reaches "alaska state" its coast 5300 km so beyond an additional 200 kilometer into alaska truly "aligns in terms of relative length" with southern honshu and Kyushu. this will teach the length accurately and although i admit imperfect it is significantly "less inaccurate" than the traditional maps and if precision is too burdensome to  at least my suggestion which i have already measured improves "less inaccurate" so simply have experts check and make only minor adjustments.
this method will teach the ural continent showing the length "less inaccurately" admittedly not precise but less inaccurately.
***review and diagram
brief summary: vertical line for 30 east in a "line due north," why 30? because western continental joint which aligns with edge of baltic sea coast near saint petersberg.
the map-introduction should list edges/borders of continent with the upgraded names as well as old name in parentheses, at 30 degrees east: the south part of "ural continent" [asia] is bordered by "nile continent" [africa] and by mediteranean sea and by black sea. "ural" continues, here i emphasize the letters in word "contin"-ue like "contin"-ent, it continues to the atlantic ocean [obviously shown on another map.] i recommend upgrading the name of the "contin"-uous "contin"-ent to "ural" representing both sides of the ural mountain range.
among the options which my colleague and i considered,  for educational purposes the western edge should be VERTICAL  and due north in contrast to  the east edge of map "based only on length so also not curved" edge of map but also VERTICAL based on length. which will result in the apparent squeezing to represent the curve of the ball "less inaccurately" than maps we have now. no need to make a curved edge as above, simply include equal length, because this will demonstrate more visibly the difference in length at the northern areas of the ball better than curving both edges with white space margins because less information.
the map should show a picture its left edge representing 30 degrees east near continental joint close to Cairo with that part of "NILE" continent [africa]. appearing basically as the following text diagram with units as above and from north:
30| LLLLLLwLwL representing edge of baltic, s.p., until alaska state same length as southern "ural".
30| WWLLLLLL.h.  representing black sea to Hokkaido island despite north and EAST of Kyushu still less length.
30| LLLLLLLLl,k=kyushu island. only 8.5 units so an equal length must include kyushu.
med. sea+land
30.30| LLLLLLLLL [not including water.] 9 units of land.
