 # Areas of Compound Shapes (Squares only)

In this worksheet, students find areas of compound shapes made from squares. Key stage:  KS 3

Curriculum topic:   Geometry and Measures

Curriculum subtopic:   Solve Problems Involving Perimeters and Areas of 2D Shapes

Difficulty level:   ### QUESTION 1 of 10

You must know the formula for finding the area of a rectangle.

Area of a rectangle = length × breadth

OR base × height

Example

Find the shaded area of the following shape. Solution

Area of large square = 13 × 13 = 169 units2

Area of small square = 5 × 5 = 25 units2

Shaded area = 169 − 25 = 144 units2
