The length of a rectangle is four more than double the width. If the perimeter is 122 inches, find the dimensions.

Question

find the dimensions.

for both width and length

Answer 1

P=122 = 2L+2W = 2(L+W) = 2(4+2W + W) = 2(4+ 3W = 8 + 6W = 122

8+6W = 122

6W = 122-8 = 114

W = 114/6 = 19 inches

L=4+2W = 4+2(19) = 4+ 38 = 42 inches
