Check 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
“If your child 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?”
