## 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

Perimeter 1

Perimeter 2

Perimeter 3

### Units of measurement (converting length units)

Basic conversion rules:

1) If you need to convert from a LARGER unit to a SMALLER unit, MULTIPLY.
For example: 5km into metres: 5 x 1000= 5.000 metres

2) If you need to convert from a SMALLER unit to a LARGER unit, DIVIDE.
For example: 10cm into metres: 10 / 100= 0,1 metres
