Area and Perimetre

Area:

Calculating area:

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.

Perimetre:

Calculating perimeter:

The perimeter is the distance all the way around the outside of a 2D shape.

To work out the perimeter, add up the lengths of all the sides


The perimeter of this shape is 10 + 10 + 6 + 6 = 32
