The concept of perimeter is simple: it's like going around a figure, and checking what distance you went. We find perimeter by adding the side lengths. The difficulty comes in remembering what the word means. I solve several different problems involving perimeter, including ones where the perimeter is given and side lengths are asked. This lesson is meant for grade 4 onwards.
