Maths Standard Year 11 - Module 2 - Lesson 2
Area of Basic Shapes
1. Key Ideas
Five formulas, one strategy: identify the shape, find the perpendicular height, substitute — and always write the unit.
- The area formula for rectangles, triangles, parallelograms, trapeziums and circles
- Why different shapes need different formulas — and what each part measures
2. Success Criteria
By the end, you should be able to:
- The area formula for rectangles, triangles, parallelograms, trapeziums and circles
- What a composite shape is
- The correct units for area answers
