Answer:

x² + 9x + 8

Step-by-step explanation:

To find the area of a rectangle, we want to multiply the length by the width.

First let's recognize the expressions of each side.

  • the length is x + 8
  • the width is x + 1

Let's multiply.

(x + 8)(x + 1)

FOIL: first – outer – inner – last

x² + x + 8x + 8

Simplify like terms.

x² + 9x + 8

This is your area.
