Perimeter Word Problems for 11 Plus: Calm Guidance for Parents
19 October 2026
Understanding perimeter word problems
Perimeter word problems often ask children to find the total length around a shape, sometimes with missing sides or in real-world contexts. For the 11+, questions might involve rectangles, compound shapes, or practical situations like fencing a garden. Reading each question carefully is key.
Key insight: Encourage your child to underline what the question is really asking. Perimeter, not area.
Spotting common 11+ perimeter questions
Typical 11+ perimeter word problems include shapes with missing sides, L-shapes, or questions comparing shapes with the same perimeter. Children may need to apply properties of rectangles, such as equal opposite sides, to find missing lengths before adding up the perimeter.
Breaking down compound shapes
When a question involves an L-shaped or other compound figure, help your child split the shape into rectangles. Find any missing sides by using the lengths of parallel sides, then add all the outer sides together to find the perimeter.
Key insight: Drawing extra lines to create rectangles can make tricky shapes much clearer.
Supporting calm problem solving at home
Perimeter word problems can feel overwhelming if rushed. Encourage your child to sketch the shape, label all sides, and tick them off as they add. This helps avoid missing a side or adding the same length twice.
