If area of a rectangle can be caluclated by mulitplying the width (w) of the room by length (l) of a room, which equation can be used to calculate the area (a)?

l + w = a

a = lw

2l + 2w = a

2l + 2w = a

Step-by-step explanation:

A rectangle room has 2 bases so the length and width needs to be doubled.

So, 2l + 2w = a  is the right answer.

Note: I don't know if you just started the lesson but there needs to be one more dimension that needs to be recognized. This dimension is called height (h). The true equation is:

2l + 2w + 2h = a

or

2(lw + lh + wh) = a
