FAQs

Question: What is the formula for the area of a triangle?
Answer: The area of a triangle can be calculated using the formula: Area = 1/2 × base × height.

Question: How do I apply Heron's formula?
Answer: Heron's formula states that the area of a triangle with sides a, b, and c is given by: Area = √[s(s-a)(s-b)(s-c)], where s is the semi-perimeter (s = (a+b+c)/2).
