Question

The length of a rectangle is 6 more than twice its width. The

perimeter is 36 inches. Find the width of the rectangle.

Answer 1

The width of the rectangle is 4 inches.

Explanation:

The perimeter is 36 inches.

The length of a rectangle is 6 more than twice its width.

`l=6+2w`

The perimeter of the rectangle is
`P=2(l+w)`.

`36=2(6+2w+w)\\18=6+3w\\3w=12\\w=4\, \text{inches}`
