Yes, the area doubles if you double either the length or the width, but NOT BOTH!

Say you have a rectangle that has the the dimensions l * w. All of a sudden, you decide to double the length, so now the area of the rectangle is 2l * w.

How does that new area compare to the old area, then? You'd take new area divided by the old area: +2lw%2Flw+. The l and the w cancel and you'll end up with two. This says that the area in the numerator is double the area in the denominator.
