Students learn how to calculate the area of composite shapes made up of triangles and rectangles.

Using right-angled, isosceles and scalene triangles the learning progresses through the level of challenge and complexity in each problem.

**Differentiated Learning Objectives**

- All students should be able to calculate the area of a triangle and rectangle.
- Most students should be able to find the area of a composite shape made from triangles and rectangles.
- Some students should be able to set up and solve equations involving composite areas.
