Answer:
The area of square 2 is 130 units square
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
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


Remember that

so


substitute in the equation A and solve for b2^2

therefore
The area of square 2 is 130 units square
