Evaluate the surface integral. s x ds, s is the triangular region with vertices (1, 0, 0), (0, −2, 0), and (0, 0, 12).

The surface integral for the given triangular region would be:

In order to determine the surface integral, we will find the perimeter of the surface:-

r(s, t)

∵

=

Now, we have

|| × || = × (

=

After solving the integral, we get the surface integral:

=  

Thus, is the correct answer.
