Calculating missing side lengths from the area of a trapezium

Maths

In this unit pupils learn how to derive and use the formula for the area of a triangle and trapezium. In the future unit, this knowledge is called upon to find the volume of different prisms and area of composite shapes

In this unit, pupils explored the relationship between perimeter and area. In particular, they considered whether a shape can have the same area and perimeter value

Perimeter and area

Calculate the area of the trapezium (you do not need to state the units).

This lesson will soon be taken down.
