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
and 
; remember that the area of a rectangle is (length)(width), so we can substitute our values to find its area:
On the other hand, the triangle attached to the top of the parallelogram has
, and 
; since the area of a triangle is 
, we can substitute our values to get:
Now the only thing lefts is add the area of the parallelogram and the triangle to get our total area:
We can conclude that the area of the figure is
.
