The perimeter of a rectangle with length l and width w is what?

Perimeter is the total distance around the figure. A rectangle has two sides of length l and two sides of width w, so you add l + l + w + w. That becomes (l + l) + (w + w) = 2l + 2w, which can be written as 2(l + w). So the perimeter is 2(l + w) because it compactly combines both dimensions.
