F(x,y,z) = i+(x+yz)j+(xy-squareroot(z)), C is the boundary of the part of the plane 3x+2y+z=1.

I know integral F dot dr = double integral curl F dot ds. I found the curl of F to be -j+k. I don't know how to set that up in the integral or what ds is. Can somebody help please??

and c is in the first octant
