What is area?

To help you understand an area, imagine painting it and how much paint you might use. Area can be worked out by multiplying the length of a shape by its height.

Length x Width = Area

You can sometimes break a shape up into two or more simpler shapes and after finding the area for each shape you add the areas together to find the total area.

This link will give you more information.
