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! :)
First, u have to find x so u set up this equation:
2x+2+3x+6=48
Then solve to get:
5x+8 = 48
5x=40
X=8
Then, u substitute 8 in the expression 3x+6:
3(8) +6
Ur final answer is 30.
