Question

The perimeter of a rectangle is 61 centimeters. The length is 4 centimeters longer than the width, w. Which equation can be used to find the width of this rectangle?

A= 2w + 2(w +4) = 61
B= 1/2w + 2 (w+4) =61
C=2w + 1/2 (w +4) =61
D= 1/2 w + 1/2 (w +4) =61

Answer 1

A

Explanation:

P=2L+2w

P=61

W=W

Since length is 4cm longer

Therefore length=W+4

General equation=2w+2(w+4)=61
