Describe the process for calculating the area of this figure

Check the picture below.

so the composite figure, is really two triangles and one parallelogram.

so we can simply get the area of those triangles, we know their base and height, and the area of the parallelogram, we also know its base and height, and sum them up, and that'd be the area of the composite.
