Answer 7

Alright,

So in the word sentence that we are given, it says, "the length of a rectangle is four times the width". We must write that into an equation.
Equation: L = 4W

Now lets put that aside for now. Now I recall that the perimeter of a rectangle is P=2L+2W.
Right?

Alright a few more seconds

Answer 9

Now this is our new equation: P=2(4W)+2W = 10W

Now we have to replace the W with 13. What does that equal?

Just multiply 13 x 10 and you have your answer! :)
