Question

The length is 3 inches more than twice the width. Which expression represents the perimeter of the frame in inches?

2w+3

Answer 1

`(6W+6)\ in`

Explanation:

we know that

The perimeter of a rectangle is equal to

`P=2(L+W)` ----> equation A

where

L is the length

W is the width

we have

The length is 3 inches more than twice the width

so

`L=2w+3` ----> equation B

substitute equation B in equation A

`P=2(2W+3+W)`

Combine like terms

`P=2(3W+3)\\P=(6W+6)\ in`
