The perimeter of a rectangle equals the sum of the lengths of its four sides. If the width of a rectangle is 4 inches and its perimeter is 36 inches, find the length of the rectangle. The length of the rectangle is ? My answer was 144, is this correct?

P = Perimeter W = Width L = Length P = 2 W + 2 L 36 = 2 * 4 + 2 L 36 = 8 + 2 L Subtract 8 to both sides 36 - 8 = 8 + 2 L - 8 28 = 2 L Divide both sides by 2 28 / 2 = 2 L / 2 14 = L L = 14 in

never mind -worked it out!!
