## Answers ( No )

w= width

l= 4w-13

Perimeter= 2l+2w

Substitute (4w-13) for l

174=2(4w-13)+2w

174=8w-26+2w

174=10w-26

Add 26 to both sides

200=10w

Divide both sides by 10

20 inches= w

Substitute the answer to find length.

l=4w-13

l=4(20)-13

l=80-13

l=67 inches

Check:

174= 2(67)+2(20)

174=134+40

174=174

Hope this helps! 🙂
