Question

Each side of a square is lengthened by 5 inches. the area of this​ new, larger square is 36 square inches. find the length of a side of the original square.

Answer 1

The formula of the area is:

$A = s^{2}$

Where s stands for side.

So if the area is 36, the lenght of the side must be:

$s = \sqrt{36}$

$\bf~s = 6$

So if 6 is the side of the original square plus 5, than the original lenght of the side is:

6 - 5 = 1 inch
