Suppose there are two persons with the same height but one of them is about 20% heavier. According to the Mosteller formula, the body surface area of the heavier person is about what percentage larger than the body surface of the lighter person?

Ifigured it out from watching a khan academy video , i am so sorry about the first answer. but i agree that x= 72. and now you can give the other person brainliest if you want.

Use pythagorean’s theorem and find the missing side lengths of the two smaller triangles and add them together
13^2 - 12^2 = 5
15^2 - 12^2 = 9
5+9 = 14
14 is the length of each side of the square
14^2 + 14^2 = 19.8
19.8 is the diagonal length of the inside if the square

The third one i'm pretty sure

Just like apples hahahahahhaa
