Perimeter of Compound Shapes
Measure and calculate the perimeter of composite rectilinear shapes in centimetres and metres
Suggested ages 9–10
Learning journey
Your child is mastering advanced measurement skills — calculating area and perimeter of shapes, working with fractions in measurements, converting between different units, and solving real-world problems involving distance, time, and volume.
Evidence of understanding
- Find the perimeter of an L-shaped figure by identifying all side lengths
- Calculate the perimeter of a composite shape where some sides must be deduced
- Draw a composite rectilinear shape with a perimeter of 40 cm
Assessment prompt
If Perimeter of Compound Shapes is given an L-shaped garden plan with all the side measurements labelled, can they add all the sides together to find the total perimeter?
