The perimeter of a rectangle is 510 cm. The ratio of the length to the width is 3:2. What are the dimensions of this rectangle?

P = 2(L + W)
510 = 2(L + W) ...divide both sides by 2
510/2 = L + W
255 = L + W

Length to width....3:2.....added = 5

3/5(255) = 765/5 = 153 cm <== length
2/5(255) = 510/5 = 102 cm <== width
