Lesson details

Lesson outcome

I can calculate the perimeter of compound shapes made from rectangles, triangles, parallelograms and trapeziums efficiently.

Show transcript
Before calculating perimeter, consider the shape and check you know the required lengths. It is not necessary to know every side length. Sometimes you can deduce the sum of a subset of side lengths. Identifying where you can be more efficient can make calculations simpler.
