As you read from the nice tutorial, there are two cases. The second case isn't too hard to find the area of the parallelogram. I will talk about the first case: how to find the area of the four triangles? They are calculated in the similar way. I think you can get the idea from this picture and my code.

Here is my solution 3363199
