Example 1 · level 1 — a gentle start
A card is 5cm by 11cm. What is its area, in cm²?
- 110
- 16
- 55
- 32
Answer: 55 — Area is 5 × 11 = 55cm².
11+ area and perimeter questions
Area and perimeter comes up in the maths paper of every major 11+ format. Here is what the questions look like, the method that works under time pressure, and five worked examples with the full reasoning, from a gentle start to a hard paper.
Maths · examined by GL and CEM · 5 worked examples
What your child needs to know
- Perimeter is the walk all the way around the edge.
- Area is the space inside: multiply the two sides.
Where marks get lost: Watch the units: cm for perimeter, cm² for area.
Worked examples
Every question below is generated by the same engine your child practises on, and every answer is derived by our checker rather than written by hand — which is why we can put them on a public page at all.
Example 2 · level 2 — typical of early practice
A card is 7cm by 6cm. What is its area, in cm²?
- 42
- 84
- 13
- 26
Answer: 42 — Area is 7 × 6 = 42cm².
Example 3 · level 3 — standard paper difficulty
A rectangle is 19cm by 12cm. What is its area, in cm²?
- 228
- 31
- 62
- 456
Answer: 228 — Area is 19 × 12 = 228cm².
Example 4 · level 4 — a harder paper
A triangle has a base of 16cm and a height of 14cm. What is its area, in cm²?
- 60
- 224
- 30
- 112
Answer: 112 — Area of a triangle is ½ × base × height = ½ × 16 × 14 = 112cm².
Example 5 · level 5 — the level that separates candidates
A triangle has a base of 30cm and a height of 68cm. What is its area, in cm²?
- 1020
- 2040
- 98
- 196
Answer: 1020 — Area of a triangle is ½ × base × height = ½ × 30 × 68 = 1020cm².
How to practise this at home
- Work in short, frequent sessions. Ten minutes daily beats an hour at the weekend, because the recall gap is what builds memory.
- Insist on written working, even for questions your child can do in their head — under exam pressure the method is what survives.
- When an answer is wrong, ask them to explain their reasoning before you correct it. The error is almost always in one step, not the whole approach.
