pav-90 [236]

Answer:

Step-by-step explanation:

The average length of the weird trapezoidal shape on the left is

(2 m + 10 m)/2, or 6 m.  The width is 4 m, so the area is 24 m^2.

The area of the semicircle is (1/2)(pi)(2 m)^2, or 2pi m^2.

Thus, the overall area of the green shape is 24 m^2 + 2pi m^2.
