For hyperbolic geometry, you can find the answers to your questions on Wikipedia. The An interesting thing is that there is an absolute upper bound on the area of a hyperbolic triangle, even though lengths are unbounded.

For spherical geometry, you can find the area of a spherical triangle here and corresponding trigonometric formulas here.
