What is the perimeter of a square with an area of 144 square inches?

Hi!

Since we know a square has sides of equal length, and to find the area of a square you square one of the side lengths, find the square root of 144.

The square root of 144 is 12.

So the means each side length is 12.

A perimeter is the distance around the square, or all of the side lengths added together.

4 sides on a square, each length is 12...
12 x 4 = 48

The perimeter is 48

Hope this helps! :)
