To find the area of the composite shape, we need to find the area of the triangle and the parallelogram separately, then add them together.
Area of the triangle:
A = 1/2 * base * height
A = 1/2 * 20 cm * 8 cm
A = 80 cm^2
Area of the parallelogram:
A = base * height
A = 15 cm * 12 cm
A = 180 cm^2
Total area of the composite shape:
Total area = area of triangle + area of parallelogram
Total area = 80 cm^2 + 180 cm^2
Total area = 260 cm^2
Therefore, the total area of the composite shape is 260 square cm.
