Area and Perimeter Quiz
15 questions · free · new questions every attempt · Updated September 26, 2026

Perimeter measures the distance around a shape and area measures the space inside. This quiz asks for both across rectangles, triangles and circles, so you practise choosing the right formula, not only applying it.
What this quiz covers
- Area of a rectangle
- Perimeter of a rectangle
- Area of a triangle
- Area of a circle in terms of π
- Circumference of a circle
- Keeping track of square units versus plain units
How to prepare
Write the formula before substituting numbers. Perimeter uses plain units (cm), area uses square units (cm²). For circles, use the radius: if you are given a diameter, halve it first. Our geometry calculator is handy for checking.
Sample questions with answers
These five questions show the style. Your quiz above will have different numbers each time.
- A rectangle is 12 cm long and 8 cm wide. What is its area?
Show answer
96 cm². Area = length × width = 12 × 8 = 96 cm².
- A rectangle is 8 cm long and 6 cm wide. What is its perimeter?
Show answer
28 cm. Perimeter = 2 × (8 + 6) = 28 cm.
- A triangle has base 8 and height 14. What is its area?
Show answer
56. Area = ½ × base × height = ½ × 8 × 14 = 56.
- What is the area of a circle with radius 2? (Give the answer in terms of π.)
Show answer
4π. Area = πr² = π × 2² = 4π.
- What is the circumference of a circle with radius 9? (Give the answer in terms of π.)
Show answer
18π. Circumference = 2πr = 2 × 9 × π = 18π.
Frequently asked questions
What is the difference between area and perimeter?
Perimeter is the length around a shape; area is the amount of surface it covers.
What is the formula for the area of a triangle?
Half the base times the height.
Why do circle answers include π?
Because circle formulas involve π exactly. Leaving π in the answer keeps it precise.
