The area ( A ) of the resulting figure:
A = s² - 4 · x²/2
A = 8² - x² / 2
A = 64 - x²/2
Answer:
The area is 64 - x² / 2.

we know that

the area of the complete square is equal to


As=b^(2)

where

b is the length side of the square


b=8m

so


As=8^(2)


As=64


the area of one corner is equal to the area of a triangle



(x^(2))/(2)

so

the area of
4 corners is equal to


(x^(2))/(2)*4=2x^(2)


the area A of the resulting figure as a function of x is equal to

area of the square minus the area of
4 corners


A=(64-2x^(2))


the answer is


A=(64-2x^(2))
