How do I do work out the area of a rectangle?

The first step is to label the sides of the rectangle. The longest side is the 'length' - put an L next to this. The shorter side is the 'width' - put a W next to this. The second step is to multiply the length and the width together. This will give you your area. To complete a question asking about area, you always have to have units. The units for the area of something is centimetres squared, the short way of writing this is 'cm²'. After the area write cm² and the answer is complete.
