How to work out an area

In this video from KS2 Maths a builder explains how to work out the area of a shape.

To work out the area of a square or rectangle, multiply its height by its width.

If the height and width are in cm, the area is shown in cm². If the height and width are in m, the area is shown in m².

A square with sides of 5 m has an area of 25 m², because 5 × 5 = 25.
