Question 766767: The perimeter of a rectangle is 54 m. The longer side is three more than the shorter side. What is the area of the rectangle? Answer by Cromlix(4381) (Show Source):
You can put this solution on YOUR website! Shorter side = x
Longer side = 3 + x
Perimeter = 2*shorter side + 2*longer side
54 = 2(x) + 2(3 + x)
54 = 2x + 6 + 2x
54 - 6 = 4x
48 = 4x
x = 12
Shorter side = 12m
Longer side = 15m
Area of rectangle = 12 * 15
Area of rectangle = 180m^2
Hope this helps.
