Question

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

Answer 1

Answer:

A = x² + 8x + 12

Step-by-step explanation:

Area of a rectangle:

A = bh

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

A = x² + 2x + 6x + 12

A = x² + 8x + 12

Answer 2

Step-by-step explanation:

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

The area of a rectangle is given by

A=a*b

So

$(x + 2) \times (x + 6) = {x}^{2} + 8x + 12$
