Calculating area of the ascribed square.


Let x be each of the two equal lengths.


a = 2x units.

a is the side length of the ascribed square.



tanb = 2x/x

b = atan(2)°


c = 180-45-atan(2)

c = (45+atan(½))°


(x/sin(45+atan(½))) = (d/sin45)

d = 0.7453559925x units.

d is the adjacent base of the blue inscribed triangle.


cos(atan(½)) = x/e

e = 1.11803398875x units.

e is the adjacent height of the blue inscribed triangle.


Calculating x.


0.5*d*e = 10

0.7453559925x*1.11803398875x = 20

0.83333333333x² = 20

⅚(x²) = 20

5x² = 120

x² = 24

x = √(24)

x = 2√(6) units.


Recall.


a = 2x units.

a is the side length of the ascribed square.

And x = 2√(6) units.

a = 2*2√(6)

a = 4√(6) units.


Are ascribed square is;



= (4√(6))²


= 16*6


= 96 square units.
