Title

I have a 3D surface, (think about the xy plane). The plane can be slanted. (think about a slope road). Given a list of 3D coordinates that define the surface( Point3D1X , Point3D1Y , Point3D1Z , Point3D12X , Point3D2Y , Point3D2Z , Point3D3X , Point3D3Y , Point3D3Z , and so on), how to calculate the area of the surface? Note that my question here is analogous to finding area in 2D plane. In 2D plane we have a list of points that defines a polygon, and using this list of points we can find the area of the polygon. Now assuming that all these points have z values in such a way that they are elevated in 3D to form a surface. My question is how to find the area of that 3D surface?
