Question

A square has a perimeter of 12 cm. do you know its area

Answer 1

its 9

Explanation:

a square has 4 sides

divide perimeter by 4 and get the perimeter of one side

then square the side or multiply the number by itself to get area

in this case 12/4=3

3*3=9

only works for squares

Answer 2

9 cm^2

Explanation:

If the perimeter of the square is 12 cm, then the length of ONE side is (1/4) of that, or 3 cm.

The area of this square is A = s^2, where s is the length of one side.

Here we have A = (3 cm)^2 = 9 cm^2.
