Key learning points
- The formula can be used to find the area of a triangle.
- There can be more than one way to find the area of a trapezium.
- The area of composite shapes can be found by splitting into shapes whose area can be found.
Common misconception
Pupils may find the area by multiplying lengths which are not perpendicular.
Area is measured in square units. The base and height of a square are perpendicular. We multiply perpendicular lengths to make square units.
Keywords
