You can put this solution on YOUR website! The perimeter of a rectangle is 32 inches and the area is 60 square inches. Find the length and width of the rectangle.
-------------
Area = l*w = 60
Perimeter = 2l + 2w = 32 --> l+w = 16
---------------
l*w = 60
Sub for w, w = 16-l
l*(16-l) = 60
l^2 - 16l + 60 = 0
--------------
(l-6)*(l-10) = 0
l = 10, l = 6
So it's l = 10, w = 6 or vice versa
