Find the value of the 2-form on the oriented triangle with vertices .

I drew the projection of the triangle on each of the coordinate planes. Now what do I do? Do I compute the area of the triangle on the plane?

Is the basically the sum of the areas in the projected planes?

The answer is . And if it is a 2 form then it has to be assigned a number to a oriented surface. Maybe I should draw a prism?

I think I got it. Its .

But if the surface is not a triangle then you can't do this right?
