Question

The perimeter of the rectangle is fifty-four feet. What is x?

A rectangle is shown. The length is labeled fifteen feet and width is labeled x.

Answer 1

P = 2L + 2W.....we will go ahead and label x for W
P = 2L + 2x
P = 54
L = 15
now we sub
54 = 2(15) + 2x
54 = 30 + 2x
54 - 30 = 2x
24 = 2x
12 = x

check..
P = 2L + 2x
54 = 2(15) + 2(12)
54 = 30 + 24
54 = 54 (correct)

the width (x) = 12 cm
