Question

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

Answer 1

Answer:

$Area = x^2 +11x + 24$

Step-by-step explanation:

Given

From the attachment, we have:

$Length = x + 8$

$Width = x + 3$

Required

Determine the area

Area is calculated as:

$Area = Length * Width$

$Area = (x+8)*(x+3)$

Open brackets

$Area = x(x+3)+8(x+3)$

$Area = x^2 +3x + 8x + 24$

$Area = x^2 +11x + 24$
