Area of Triangles and Composite Shapes

Progressing on from finding the area of a triangle students 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.

At the start of the lesson students recap finding the area of triangles and rectangles.  The plenary links composite areas to setting up and solving equations.

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.
