Question

Please help.. what is the function rule for the perimeter P of a building with a rectangular base if the width w is two times the length L?
A.) P=2L B.) P=6L C.) P=6w

Answer 1

Someone help please...

Answer 2

\[\large P=2L+2W\]This formula makes sense I hope? If not, I can draw a picture.
We're also told to consider the Width being twice as long as the length.
We can write that as so,\[\large W=2L\]We'll plug that into our Perimeter equation,\[\large P=2L+2W \quad \rightarrow \quad P=2L+2(2L)\]Understand how we did that? Able to simplify it from there? :D

Yes, thank you! (:
