Answer:

54 cm ^ 2, 75.6 cm ^ 2, 129.6 cm ^ 2

Step-by-step explanation:

Equation for a triangle is A = (1/2) * b * h

Area of small triangle on the left: 0.5 * 9 * 12 = 54 cm ^ 2

Area of small triangle on the right: 0.5 * 12.6 * 12 = 75.6 cm ^ 2

Area of entire triangle: 54 + 75.6 = 129.6 cm ^ 2
