In the figure, it forms two polygons, a trapezoid and a right triangle.

So to determine the area of the given figure, solve the area of each polygon.

For the trapezoid, apply the formula:



Plug-in b_1=20m, b_2=12m and h=3m.



Hence, the area of trapezoid is 33 m^2.

And for the right triangle, use the formula:



Substitute b=20m and h=4m.



So the area of the right triangle is 40 m^2.

Then, add the area of the two polygons to get the total area of
the given figure.



Thus, the area of the figure is .

THIS SHOULD BE 48 INSTEAD OF 33
