Draw each and every and then draw a diagonal from between the vertices to the different. Then use portion of a triangle to calculate each and every of the two triangles of quadrilateral (section = a million/2 base * top)

Raj's suggestion will always work if the quadrilateral is convex. But if it is concave (a chevron) you need to choose the diagonal that is entirely contained in the quadrilateral. If one of the diagonals is outside the quadrilateral, choose the other one.
If you choose a good diagonal, you only need to use one of them.
