What is the area of a square whose perimeter is 12?

We know that a square has an equal height and width. So if all 4 sides, which are equal in length, add up to 12, then we can find the length of one side by dividing 12 by 4:

12/4 = 3

If the length of one side is 3, we can multiply the height (3) by the width (3) to find the area.

3*3 = 9

Answer: the area of the square is 9.

P=4L

12=4L

3=L

A=L^2

A=3^2

A=9
