I constructed the figure with the information that you provide, please check the picture.
Since there is a right triangle inside the parallelogram, the parallelogram is a rectangle with
length=20in and
width=16in; remember that the area of a rectangle is (length)(width), so we can substitute our values to find its area:

A=(20in)(16in)

A=320in^(2)
On the other hand, the triangle attached to the top of the parallelogram has
base=20in, and
altitude=8in; since the area of a triangle is
(1)/(2) (base)(altitude), we can substitute our values to get:

A= (1)/(2) (20in)(8in)

A=80in^(2)

Now the only thing lefts is add the area of the parallelogram and the triangle to get our total area:

totalA=320in^(2) +80in^(2) =400in x^(2)

We can conclude that the area of the figure is
400in^(2).
