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 - 1.5
  • We 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
