How to find area

Area is a measure of how much space there is inside a shape.

In order to find an area value, using the grid method,
we need to know the size that a grid square represents.

This example uses centimetres but the same method applies for any unit of length or distance. You could, for example be using inches, metres, miles, feet etc.
In this example each grid square has a width of 1cm and a height of 1cm.

Count the grid squares inside the large square to find its area.
There are 16 small squares so the area of the large square is 16 square centimeters.
In mathematics we abbreviate 'square centimeters' to cm².
The 2 means ‘squared’. Each grid square is 1cm².
The area of the large square is 16cm².
