Question 259776: The perimeter of a rectangle is 68 inches. The length is 2 inches longer than 3 times the width. Find the width Answer by CharlesG2(834) (Show Source):
You can put this solution on YOUR website! The perimeter of a rectangle is 68 inches. The length is 2 inches longer than 3 times the width. Find the width
perimeter P = 2 * (L length + W width)
68 = 2 * ((3W+2) + W)
68 = 2 * (3W + 2 + W)
68 = 2 * (4W + 2)
68 = 8W + 4
64 = 8W
8 = W
check:
68 = 2 * (3*8 + 2 + 8)
68 = 2 * (24 + 2 + 8)
68 = 2 * 34
68 = 68
