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
