Question

Help pleaseee a s a p

Answer 1

I am just going to assume that the non-shaded box is a square, and tha its side lengths are equal to x.

A.

`Area = 8^(2) - x^(2)`
This is because the area of the shaded is the area of the bigger square minus the area of the smaller.

B.

`Area = 8^(2) - x^(2) \\ Area=8^(2)-3^(2) \\Area=55cm^(2)`
This is found by just plugging in the value of x into the previous expression.
