Answer:
6(5+2y)
Step-by-step explanation:
We have width = w = 5+2y
L = length of the rectangle
Length has been give to be 2 x width
Width = w
So l = 2w
Perimeter of a rectangle = 2(l+w)
Since l = 2w, we have
2(2w+w)
= 2(3w)
= 6w
So since we already know w = 5+2y
We put this value into 6w
Then we will have this expression:
P = 6(5+2y)
