The area of a square is equal
to one side (a) multiplied by
another side (a). Since each
side of a square is the same,
it can simply be the length
of one side squared.

square = a x a = a 2

Example: If a square has one side of
4 inches, the area would be 4 inches
times 4 inches, or 16 square inches.
A = 4 x 4
A = 16 in.
