What is the formula for finding the area of a triangle using Heron's formula?
What is the formula for finding the area of a triangle using Heron's formula?
- A = 1/2 * (a + b + c), where a, b, c are the sides
- A = 1/2 * base * height
- A = πr^2, where r is the radius of the inscribed circle
- A = √(s(s-a)(s-b)(s-c)), where s is the semi-perimeter and a, b, c are the sides (correct)
