Question

How do you Express the area of the entire rectangle.

Answer 1

x^2+6x+8

Explanation:

The initial way to represent the area of the entire rectangle is (x+2)*(x+4).

With this, we can multiply the two together using the FOIL method (First, Outside, Inside, Last).

x*x=x^2
x*4=4x
2*x=2x
2*4=8

Add these together, and you get your final answer:
x^2+6x+8

Answer 2

x^2+6x+8 or (x+2)*(x+4)

Explanation:

area = length * width

area = (x+2)*(x+4)

(just expanded the brackets)

area = x^2+6x+8
