The length of a rectangle is twice the width. The perimeter of the rectangle can be expressed as 3 x 13.7 . What is the width.

Answer 1

Hi Rahul, the perimeter of a rectangle can be found using: P = 2L + 2W, where P is the perimeter, L is the length, and W is the width.

Given:

L = 2W

Rewrite equation using only W:

P = 2 * (2W) + 2W

Substitute for P and find W:

4W + 2W = 3 * 13.7

6W = 41.1

Divide by 6:

W = 6.85

The width is 6.85
