The area of a square is
where
b is the length side of the square
Let
b1 ----> the length side of square 1
b2 ----> the length side of square 2
b3 ----> the length side of square 3
Applying the Pythagoras Theorem
-----> equation A
we have

10. The two sides are equal because that is the definition of a midpoint so
8x+11=12x-1

12=4x
12/4=3
X=3
