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.

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.

Area - The area is the size of the surface and states the number of unit squares needed to completely cover that surface.
Trapezium - A trapezium is a quadrilateral with exactly one pair of parallel opposite sides.
Trapeziums/trapezia - The plural of trapezium can be referred to as trapezia or trapeziums.
Composite rectilinear shape - A composite rectilinear shape is a composite shape made from rectangles.
