Question

The length of a rectangle is three inches more than four times the width. The perimeter of the rectangle is 56 inches. What is the width of the rectangle?​

Answer 1

The width of the rectangle is 5 inches.

Explanation:

Perimeter of a rectangle: 2L+2W where L=length and W=width

P=56

56=2(4W+3)+2W

56=8W+6+2W

56=8W+2W+6

56=10W+6

56-6=10W

50=10W

W=50/10=5

W=5

L=4W+3=4(5)+3=20+3=23
