In this activity, we're going to be calculating the area of some rectangles.

The area of a 2D shape is the total amount of surface space it covers.

Let's have a look at an example:

To calculate the area of this square we **multiply the** **length (l) by the width (w) **

We know that all sides of this shape will be 10 cm as it is a square.

**10 cm x 10 cm = 100 cm**

Now we add this special symbol to show that the answer is a measure of area: **²**

We add this after the unit of measure, so the answer is** ****100 cm².**

We read this as 100 cm squared.

In the following questions, we are going to work out the area of some shapes, and in some questions use the area to find the measurements.

**Things to remember:**

When calculating the area of a rectangle we multiply l by w

We must remember to include the correct unit of measure.

We read the area as squared and add the squared symbol after the unit of measure (²)

Good luck!
