When measuring a 2D shape, like a square or a rectangle, it is useful to know what the perimeter and area of a shape are. The perimeter is the total distance around the outside of a two-dimensional shape. Area is the amount of space covered by the shape's surface. To work out the area of a rectangle multiply the length of its longest side by the length of its shortest side. This will give you an answer in square mm, cm or m (mm2 cm2 or m2).

To calculate the perimeter of a 2D shape, add together the length of each side
|
100cm = 1m That's way too big for a 'phone!

A square has four equal sides, therefore the perimeter will be 4 x 6 = 24
|
A rectangle has two sides of equal length and two more side with equal length. So the answer is:
(2 x 5) + (2 x 9) which is 10 + 18 = 28 |

As a square has four equal sides, we divide by 4 to get the answer
|
Area is measured in square mm cm m or km

Cubed cm are written as cm3
|
Millimeters and centimeters would be way too small and kilograms measure weight!

This would be a very small notebook measuring 4cm x 6.5cm
|
Squared paper helps to work out the area of irregular shapes too
