Area of triangle in 3D = ( \frac\sqrt32 \times (\textside length in plane)? ) Easier: Triangle vertices: (1,0,0), (0,1,0), (0,0,1). Side vectors: (-1,1,0) and (-1,0,1). Area = ( \frac12 | (-1,1,0) \times (-1,0,1) | = \frac12 | (1,1,1) | = \frac\sqrt32 ).

[ (\nabla \times \mathbfF) \cdot \mathbfn = (-1,-1,-1) \cdot \frac(1,1,1)\sqrt3 = -\frac3\sqrt3 = -\sqrt3 ] So RHS = ( \iint_S (-\sqrt3) , dS = -\sqrt3 \times \text(surface area) ). Area = ( \frac12 | (-1,1,0) \times (-1,0,1)
