Answer:
L + L + W + W
Explanation:
To find the perimeter of a rectangle, you add the Lengths and Widths. So for a rectangle if the width was 1 and the length was 2, you would do 2 + 2 + 1 + 1, which would get you 6. This is different from the area because in the area you multiply L x W, because you are finding the area inside the shape. With finding the perimeter, you are finding the length of the outside.
