Area

By the end of this worksheet, you will be able to:

• Solve problems involving the area of a rectangle.
• Solve problems involving the area of irregular shapes.

Key Points:

• Area is the amount of space taken up by a shape or surface and it is measured in square units e.g. cm2 or m2.
• If we were given a shape drawn on a grid, we can find the area by counting the number of square units used to make the shape.
• The area of a rectangle may be calculated by multiplying the length by its width: Area = Length x Width.
• If the area and the length, or the area and the width of a rectangle are given, we can calculate the missing dimension by using either of the formulae below:

Length = Area ÷ Width
Width = Area ÷ Length
