Guide to Scale drawings: Explanation, Diagrams & Worked Examples

Explanation:

A scale drawing shows a real object reduced in size using a fixed ratio. A scale may be given with units (e.g. 1 cm represents 5 m) or as a unitless ratio (e.g. 1 : 500, which means 1 cm on the drawing = 500 cm in real life).

To find a real-life length, measure the drawing length in cm and multiply by the scale. To find a drawing length, divide the real-life length by the scale (converting to matching units first if needed).

Example 1: A map has a scale of 1 : 25,000. Two villages are 6 cm apart on the map. Find the real distance in km.

N Scale 1 : 25,000 Village A Village B 6 cm
Real distance = 6 × 25,000 = 150,000 cm
150,000 ÷ 100 = 1500 m = 1.5 km

Example 2: A plan uses a scale of 2 cm to 5 m. A rectangular garden is 17.5 m long by 10 m wide. Find its length on the plan.

Garden Plan 4 cm (10 m) ? cm (17.5 m) 2 cm = 5 m
Scale for 1 cm: 5 m ÷ 2 = 2.5 m per 1 cm
Plan length = 17.5 ÷ 2.5 = 7 cm

GCSE Past Paper Scale drawings Questions & Answers

Past Paper Example 1 AQA Jun 2022 2F Q15 3 marks
The scale drawing shows a tree and a student.
The tree has drawn height 7 cm.
The student has drawn height 2.5 cm.
7 cm2.5 cm
The actual height of the tree is 4.2 metres.
Work out the actual height of the student.
Worked Solution & Mark Scheme (3 marks)
Scale factor: 7 cm = 4.2 m ⇒ 1 cm = 4.2 ÷ 7 = 0.6 m M2
Actual height of student = 2.5 × 0.6 = 1.5 m. A1
7 cm2.5 cmScale: 7 cm = 4.2 m (0.6 m/cm) → Student = 1.5 m
Answer: Answer 1.5 m
Past Paper Example 2 AQA Nov 2022 3F Q17 3 marks
This scale drawing of a bus has length 8 cm
Scale: 1 cm represents 1.65 m
8 cmScale: 1 cm represents 1.65 m
Work out the actual length of the car.
Give your answer in metres, to the nearest centimetre.
The actual length of the bus is 3.8 times the actual length of a car.
Worked Solution & Mark Scheme (3 marks)
Actual length of bus = 8 × 1.65 = 13.2 m M1
Actual length of car = 13.23.8 ≈ 3.47368 m M1
To the nearest centimetre (2 d.p.): 3.47 metres A1
8 cmScale: 1 cm represents 1.65 mBus = 8 × 1.65 = 13.2 m; Car = 13.2 / 3.8 = 3.47 m
Answer: Answer 3.47 metres
Past Paper Example 3 AQA Nov 2020 2F Q19 3 marks
A scale drawing shows the positions of P, Q and R.
Not drawnaccuratelyP×Q×R×
Work out the scale.
On the scale drawing
PQ = 4 cm   QR = 6.5 cm
The actual distance PQ is 50 metres less than the actual distance QR.
Worked Solution & Mark Scheme (3 marks)
Difference on drawing = 6.5 - 4 = 2.5 cm M1
Difference in actual distance = 50 metres M1
2.5 cm = 50 m ⇒ 1 cm = 50 ÷ 2.5 = 20 m A1
Not drawnaccuratelyP×Q×R×6.5 - 4 = 2.5 cm = 50 m → 1 cm = 20 m
Answer: 1 cm represents 20 metres
