What is Area?Area is the amount of space a surface or 2D shape covers.
Area is defined as the number of one by one squares a surface covers.

What is Area?Area is the amount of space a surface or 2D shape covers.
Area is defined as the number of one by one squares a surface covers.
1m
1m
= 1m2
Because area is measured in squares, we always use
square units.

Why is Area useful to know?Area is used in a huge number of fields.
Landscaping
Decorating
Manufacturing

Because area is defined as the number of 1 by 1 squares a shape covers, if we split it up into columns and rows, each 1m wide in this case, it will show us how many squares the shape covers.

3m
So the area of this 3m by 3m square is 9m2.
Be cause the height is the number of rows and the width is the number of columns, the area is the height multiplied by the width.

Examples
3m
5m
To work out the area we multiply the width by the height.
5m x 3m = 15m2

This is the same as counting the number of 1 by 1 squares the shape covers.

ExamplesWhen working with larger shapes, counting the number of squares can be very time consuming.

This is why multiplying adjacent sides (sides next to each other) is more often used.
