Calculate the areas of these shapes.
Shape A is a parallelogram and shape B is a trapezium.
Area of parallellogram = b × h
Area of trapezium is a + b2 × h
Shape A is a parallelogram. The area is b × h = 10 × 4 = 40cm2
Shape B is a trapezium. The area is 12 (a + b) × h = 12 (2 + 5) × 3 = 3.5 × 3 = 10.5cm2
