    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
