Heron’s Formula Calculator
Calculate the area of a triangle using Heron’s formula with our online calculator.
What is the Heron’s Formula Calculator & How does it work?
Heron’s formula is a method for calculating the area of a triangle when you know the lengths of all three sides. It states that if a triangle has sides of lengths a, b, and c, then its area, A, can be calculated using the formula:This formula is particularly useful when you don’t have the height of the triangle or when working with oblique triangles where the height might not be easily determined.
A = sqrt{s(s-a)(s-b)(s-c)}
s = semi-perimeter of the triangle, calculated as (a + b + c) / 2

Frequently Asked Questions
How do I use Heron's formula to find the area of a triangle?
First, calculate the semi-perimeter s = (a + b + c) / 2. Then, use the formula A = sqrt(s(s-a)(s-b)(s-c)) to find the area.
What is Heron's formula?
Heron's formula calculates the area of a triangle when you know the lengths of all three sides using the formula A = sqrt(s(s-a)(s-b)(s-c)), where s is the semi-perimeter.
Can Heron's formula be used for any type of triangle?
Yes, Heron's formula can be used for any triangle, including scalene, isosceles, and equilateral triangles.
Why is Heron's formula useful?
Heron's formula is useful when you don't have the height of the triangle or when working with oblique triangles where the height might not be easily determined.
What does 's' represent in Heron's formula?
's' represents the semi-perimeter of the triangle, calculated as (a + b + c) / 2.
Can I use Heron's formula if I only know two sides and an angle?
No, Heron's formula requires the lengths of all three sides. If you have two sides and an angle, you might need to use a different method or first calculate the third side.
Is there a limit to the size of the triangle I can use Heron's formula on?
Heron's formula can be used for any triangle as long as the side lengths satisfy the triangle inequality theorem (the sum of the lengths of any two sides must be greater than the length of the remaining side).
