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
Hope this helped :)
