If the area of a square is 64 square centimeters, whats the length of one side?

A. 8cm

B. 32cm

C. 16cm

D. 4cm

It would be A because a square has four equal sides. To determine if this is right, you would find the square root of 64 which is 8. To check, find the answer to 8 to the power of two or 8 times 8 which is 64.

It's A. 8x8 is 64. Therefore, 8cm is correct.
