Check understanding
- Calculate the area of a parallelogram with base 8 cm and height 5 cm
- Calculate the area of a triangle with base 12 cm and height 7 cm
- Explain why the area of a triangle is half the area of a related parallelogram
“If your child is cutting triangular pieces of cloth where the base is 8 cm and the height is 5 cm, can they use a formula to work out the area of each piece?”
