# Math Help - Surface Integral

1. ## Surface Integral

Evaluate the surface integral ∫ ∫ (x+y) ds where D is the part of the plane x+2y+3z=6 above the triangle in the xy-plane with vertices at (0,0,0), (1,0,0), and (1,1,0).

I get 1/2 aqrt(14/9) as final answer. Is it correct?

2. ## Re: Surface Integral

Yes, that's what I get.
