    252 square feet

    Step-by-step explanation:

    Ok so the question is basically an area question. We know it is an area question because it is asking about how much carpeting a 2d thing is needed. So as we know area is l*h (Length * Height).

    So what we do is take the 12 and multiply it by 21 to get the amount of carpeting needed. When we do 12*21 we get 252 square ft.

    Therefore, Theresa needs 252 square ft. of carpeting to cover her entire family room.
