Try drawing a rectangle around the parallelogram. If
you can work out the area of the rectangle and the areas of the
parts of the rectangle outside the parallelogram, then you should
be able to find the area of the parallelogram.

Don't forget that you can break up complicated shapes into simpler small shapes (such as triangles and rectangles) whose areas are easier to find.
