What is Heron's formula?
Understand the Problem
The question is referring to Heron's formula, which is used to calculate the area of a triangle when the lengths of all three sides are known. It seeks to understand what Heron's formula is and how it can be applied.
Answer
Heron's formula calculates the area of a triangle using side lengths: A = √(s(s-a)(s-b)(s-c)), s = (a + b + c) / 2.
Heron's formula is used to find the area of a triangle when the lengths of all three sides are known. It is given by the formula: A = √(s(s-a)(s-b)(s-c)), where s is the semiperimeter of the triangle: s = (a + b + c) / 2.

Heron's formula is used to find the area of a triangle when the lengths of all three sides are known. It is given by the formula: A = √(s(s-a)(s-b)(s-c)), where s is the semiperimeter of the triangle: s = (a + b + c) / 2.
More Information
Heron of Alexandria, a mathematician and engineer from the 1st century, is credited with this formula. Heron's formula is particularly useful because it can calculate the area of a triangle without needing the height.
Tips
A common mistake is not calculating the semiperimeter correctly before applying the formula. Make sure to add all sides and divide by two to get the correct semiperimeter.
