The length of a rectangle is 2 units shorter than one-fifth of the width, x.
Enter an expression in the box that represents the perimeter of the rectangle.
Note: Use one variable and a fraction in the answer.
-----
Perimeter = 2(length + width)
length = (1/5)w-2
width = w
--------------------
P = 2[(1/5)w-2 + w]
P = 2[(6/5)w - 2]
P = [(12/5)w-4]
