Question

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

Answer 1

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

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`
