You get perimeter by adding all the sides, so:
3w+7+3w+7+w+w=438

solve for w

anonymous · Answer

That will be your width, then plug it into 3w+7 to get the length

Thank you so much! You are a lifesaver!

anonymous · Answer

what did you get for width?

anonymous · Answer

I got 53?

anonymous · Answer

Yep so the length is expressed as 3w+7
put 53 in for w and youll get the length

anonymous · Answer

So the length is 166...I got it! Thank you!
