I am trying to find the perimeter of a Rectangle,
However I think I am doing something wrong.
The length of a rectangle is four times its width. If the area of the rectangle is 144in^2, find its perimeter.
Ok, so first things first, I find that L=4W
2L+2w=144in^2
144*144=20736 in or 1728 ft
2(4w)+2w=1728ft
8W+2W=1728ft
10w=1728ft
/10 /10
w=172.8ft
Did I do this correctly?
