Guide to Area of compound shapes: Explanation, Diagrams & Worked Examples

Download Printable One Page Guide (PDF)

Explanation:

A compound (composite) shape is made up of two or more simple shapes joined together. To find its area, draw a dotted line to split it into rectangles or triangles, work out any missing side lengths first by comparing parallel horizontal and vertical sides, and then add the separate areas together.

Remember the key area formulas: Rectangle = length × width, and Triangle = 12 × base × perpendicular height. For shaded region questions, calculate the outer area minus the unshaded inner area.

Example 1: An L-shape has total width 10 cm, total height 8 cm, top width 4 cm, and right height 3 cm. Find its area.

4 cm 8 cm 10 cm 3 6 cm
Left = 4 × 8 = 32 cm²
Right = (10−4) × 3 = 18 cm²
Total = 32 + 18 = 50 cm²

Example 2: A pentagon has a 6 m by 4 m rectangular base and a triangle on top. Total height is 7 m. Find the area.

6 m 4 m 3 m 7 m
Rect = 6 × 4 = 24 m²
Tri h = 7 − 4 = 3 m
Tri = 12×6×3 = 9 m² → 33 m²

GCSE Past Paper Area of compound shapes Questions & Answers

Past Paper Example 1 IGCSE Jun 2021 1F Q18 / 1H Q3 4 marks
The diagram shows the shape ABCDE.
The area of the shape is 91.8 cm2
ABCDEx cm8 cm14 cm13 cmDiagram NOTaccurately drawn
Work out the value of x.
Worked Solution & Mark Scheme (4 marks)
14x + ½ × 6 × (13 − x) = 11x + 39 = 91.8 M2
⇒ 11x = 52.8 M1
⇒ x = 4.8 A1
Answer: x = 4.8
Past Paper Example 2 Specimen Set 1 1F Q23 / 1H Q4 4 marks
A pattern is made using identical rectangular tiles.
11 cm7 cm
Find the total area of the pattern.
Worked Solution & Mark Scheme (4 marks)
Let length = l and width = w. l + w = 7 and 2l + w = 11 ⇒ l = 4 cm, w = 3 cm M2
Area of 1 tile = 4 × 3 = 12 cm² M1
Total area = 4 × 12 = 48 cm². A1
Answer: 48 cm²
Past Paper Example 3 IGCSE Jun 2025 1F Q17 4 marks
The diagram shows the plan of a stage.
The stage is made up of a rectangle and an isosceles triangle.
6 m8 m3 mDiagram NOTaccurately drawn
Yuko is going to cover the stage with varnish.
She needs to buy enough tins of varnish to cover the stage with one coat of varnish.
Each tin of varnish covers an area of 4 m2
Work out the smallest number of tins of varnish that Yuko needs to buy.
Show your working clearly.
Worked Solution & Mark Scheme (4 marks)
Rectangle area = 6 × 8 = 48 m² M1
Triangle area = ½ × 6 × 3 = 9 m² M1
Total area = 48 + 9 = 57 m² M1
57 ÷ 4 = 14.25 ⇒ 15 tins A1
Answer: 15
