Answer:
Area = 225
Step-by-step explanation:
You use Pythagoras to figure this question out.
Because square have equal lengths.
You figure the side of them by square rooting the area by two.
Which gave me 25 of the hypetunse for the triangle and 20 for the base of the triangle.
I then use Pythag.
20² + b² = 25²
b = 15
So now I know the length of the square, we need to find the area.
15 × 15 = a
Area = 225
Hope this helped!
