Express the area of the entire rectangle. Your answer should be a polynomial in standard form
mash [69]

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
