Question

A Rectangle has a perimeter of 78 inches. The width,w is 4 less than twice the length. What is the width of the rectangle?

Answer 1

Step by step explanation:

Let width = w, let length =
Perimeter = l + l + (2l - 4) + (2l - 4)
78 = 2l + 2l - 4 + 2l - 4
78 = 6l - 8
86 = 6l
14.3 = l

Therefore w = (2l - 4)
w = (2 x 14.3 - 4)
w = 24.7

Answer: width is 24.7 inches

Answer 2

The width would be 54 inches.
