How to explain perimeter - word problems in perimeter to your student: Example question
31 October 2026
Perimeter word problems help children connect maths to real-life situations. Understanding how to add the lengths of all sides is a key skill for the 11+ exam.
Worked example
A rectangular garden is 7 metres long and 5 metres wide. What is the perimeter of the garden?
Step 1: Write down the lengths of all sides. A rectangle has two sides of 7 metres and two sides of 5 metres.
Step 2: Add all the sides together. 7 + 7 + 5 + 5
Step 3: 7 + 7 = 14
Step 4: 5 + 5 = 10
Step 5: 14 + 10 = 24
The perimeter of the garden is 24 metres.
After working through this example, your child will spot when a question is asking for the perimeter. They will be ready to practise similar perimeter word problems on their own.
