About this worksheet
Perimeter is the distance around a shape; area is the surface inside it. For a rectangle, perimeter = 2 × (length + breadth) and area = length × breadth. For a square, perimeter = 4 × side and area = side × side.
Tips for parents and teachers
- Ask the child to draw a rough figure and write the measures on it before using a formula.
- Units matter: perimeter is in cm or m, area is in square cm or square m.
- Measure a real book or table top and find both. It makes the difference between the two clear.
