We'll call the sides of the triangle a, b, and c, and the angles, A, B, and C.

If you have all three sides, you'll use. Heron's formula., and the formula for the area of a triangle.

If you have two sides and an angle, you'll use the formula for the area given two angles and a side. A = 1/2ab (sin C).
