Hi!
Since we know a square has sides of equal length, and to find the area of a square you <em>square</em> 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! :)
<span> What we are going to do for this case is find the cost for each case:
