Question

Find the area of the shaded polygon.

I would like both answers and how to get them (show work).

Thanks!

Answer 1

9) 470

10) 672

Explanation:

Question 9 equation:
`34*21 - √(34^2-16^2) * (16)/(2) = 714 - 30 * 8 = 714 - 240 = 474`.

Question 10 equation:
`16*28 + (42-28) * (32)/(2) = 448 + 14 * 16 = 448 + 224 = 672`.
