Calculate the area of the following composite shape:
3 shapes: 1. Triangle, 2. Rectangle, 3. Semi-Circle
Area of Triangle = ½bh
A = ½ x 30cm x 40cm = 600cm2
Area of Rectangle = L x W
A = 50cm x 40cm = 2000cm2
Area of Semi-circle = ∏r2/2
A = ∏ x 202 /2 = 628.32cm2
Area of Composite Shape: 1 + 2 - 3
A = 600cm2 + 2000cm2 - 628.32cm2 = 1971.68cm2
