Question

Express the area of the entire rectangle.
Your answer should be a polynomial in standard form.

Answer 1

Explanation:

Let a=x+2 and b=x+6

The area of a rectangle is given by

A=a*b

So

`(x + 2) * (x + 6) = {x}^(2) + 8x + 12`

Answer 2

A = x² + 8x + 12

Explanation:

Area of a rectangle:

A = bh

A = (x + 6)(x + 2)

A = x² + 2x + 6x + 12

A = x² + 8x + 12
