Remember, when you find the area of a shape you are measuring the size of the surface or the space occupied by the shape.

 

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.

 

You can also just count up all of the squares inside the shape, this is particularly useful if the shape is not a square or a rectangle. If there are half squares inside the shape, then you will need to join two of them together to make a whole square.
