Q:
the perimeter of a rectangle is 124 cm. the length is six more than three times the width. what are the dimensions of the rectangle?
Accepted Solution
A:
P = 2(L + W)
P = 124
L = 3W + 6
124 = 2(3W + 6 + W)
124 = 2(4W + 6)
124 = 8W + 12
124 - 12 = 8W
112 = 8W
112/8 = W
14 = W <=== width is 14 cm
L = 3W + 6
L = 3(14) + 6
L = 42 + 6
L = 48 <=== length is 48 cm
