Answer:

68.8 cm^2

Step-by-step explanation:

1. Divide the figure into a triangle and square

2. Calculate the area of the square that should be on the right side of the figure

(8.6 cm* 6.4 cm) = 55.04 cm^2

3. Calculate the bottom of the triangle

12.9 cm - 8.6 cm = 4.3 cm

4. Calculate the area of the triangle

A = .5bh

  = .5*4.3 cm* 6.4 cm = 13.76 cm^2

5. Add the square and triangle area together

13.76 cm^2 + 55.04 cm^2 = 68.8 cm^2
