## Composite 2D Figure

Then students are asked to create a shape with the same perimemter but different area. This can be a challenge.

I will break this section into two parts. Add these separate areas for each rectangle up together to find the total perimeter of composite figures of the compound shape. Example 1 of how to do it: It is done differently with both examples, but the basic maths is the same.

You work out the area of each rectangle and then add them together. The last method to work out the area for this compound shape is a little different. Instead of adding the area of two rectangles perimeter of composite figures like the previous examples you can do something very different: Work out the area a large shape around the compound shape.

In this case, you can do perimeter of composite figures to work out the area of the compound shape and the small area of a shape that has been cut out! This is represented by the green lines on the example.
