The width of a rectangle is 4n - 1.5 feet and the length is 1.5n + 4 feet. Find the perimeter of the rectangle. The perimeter of the rectangle is feet.
(Simplify your answer. Use integers or decinals for any numbers in the expression.)

Answers

Answer:

11n + 5

Step-by-step explanation:

First, what is the perimeter of a rectangle referring to? It's referring to the outside surrounding the rectangle. You just need to know that the formula for a rectangular perimeter is:

2(L+W) (W = width, L = length)

We are given width: 4n - 1.5We are given length: 1.5n + 4

Now substitute those values for the formula.

2 (4n-1.5 + 1.5n + 4)2 (5.5n + 2.5)11n + 5
