What’s the area in polynomial standard form

Note that the Area of a rectangle is given by
Area = LB

Where L is the Length (the longer side) and B is the Breadth (or Width which is the shorter side).

From the image, L is (x+6).
Also from the image, B is (x+2)

This implies:

Open up the bracket by multiplying both terms:

Since the question says to leave it in polynomial form, that is your answer. Hope I helped? ☺️
