7. If the area of a square is 64 square centimeters, what's the

O A. 8 cm

O B. 4 cm

O C. 32 cm

O D. 16 cm

If you're asking what the perimeter is:

C 32cm

If you're asking what the length of a side is:

A 8cm

Step-by-step explanation:

Area of a square is calculated by length x width.

And all four sides of a square are equal in length.

Area: 8cm*8cm=64cm2

Perimeter: 8cm + 8cm + 8cm + 8cm = 32cm

Another way to find the length of the sides would be to take the square root of 64. I believe that only works with the area of a square though.

√ (64) = 8
