Hello!
The area of a square can be found using the following formula:
area = (length) x (width)
We know that all sides of the given square are 8 inches in length. Therefore, the length and width must both be 8 inches. Insert any known values into the equation above:
area = (8 in) x (8 in)
Simplify the right side:
area = 64 square inches
We have now proven the area of the square to equal 64 square inches.
I hope this helps!
