What is the formula to find the area of a triangle?

The area of a triangle can be calculated using the formula: Area = 1/2 * base * height. Alternatively, for a triangle with sides a, b, and c, Heron’s formula is used: Area = √[s(s-a)(s-b)(s-c)], where s is the semi-perimeter, s = (a + b + c) / 2.
