+3693 Alrighty- ethan! I figured it out!
The area of a parallelogram is this: Area = (base)(height)
The area of a triangle is this: Area = 1/2(base)(height)
The height of the parallelogram is 8 and the base is 20. Therefore:
Area = (8 cm)(20 cm)
Area = 160 cm^2
The upside down triangle then has a base of 6. We already know that the two bases equal 20, so 20 – 14 = 6. The triangle also has a height of 12.6. So....
Area = 1/2 (6 cm)(12.6 cm)
Area = 1/2 (75.6)
Area = 37.8 cm^2
Now, to find the area of the whole figure, you would just add the two areas together...
160 + 37.8 = 197.8
So, the area of the figure is 197.8 cm^2!!!
