The area of a shape is the amount of space inside the shape.
To work out the area of shapes made of squares, we count the squares inside the shape.
Calculate the area of this shape in cm2.
Each unit square is 1 cm by 1 cm.
Count the squares.
There are 9 squares.
Area is 9 cm2.
We read this as "nine centimetres squared".
If the lengths are in metres, the area will be in m2.
