Question

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

Answer 1

Answer:

$(6W+6)\ in$

Step-by-step 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

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