Dylan uses the expressions (x2 – 2x + 8) and (2x2 + 5x – 7) to represent the length and width of his bedroom. Which expression represents the area (lw) of Dylan’s room?

Answer 1

isn't area = length x width ?
so ...

area = (x^2 - 2x + 8)(2x^2 + 5x - 7)

Answer 2

Length = 4 + x
Width = x
Height = x 2 + 1

What is the base area?
