We can split this composite shape into two different shapes: A Rectangle and a right angled triangle. Area of rectangle: Length * Width = 12cm * 14cm = 168cm^2
Area of the triangle: (Base * Height) / 2 = (12cm * 8cm) / 2 = 96cm/2 = 48cm^2
Lastly, we just need to add up both of our area’s to come up and solve for our area of the composite shape:
