## What is Heron's formula and how it is calculated ?

Heron's formula (sometimes called Hero's formula), named after Hero of Alexandria, gives the area of a triangle when the length of all three sides are known. Area = √[s(s−a)(s−b)(s−c)] Where s is the semi-perimeter of the triangle and a, b and c are three sides of the triangle.

## How to Calculate Heron's formula?

Heron's formula calculator uses Area=sqrt(Semiperimeter Of Triangle *(Semiperimeter Of Triangle -Side A)*(Semiperimeter Of Triangle -Side B)*(Side A+Side B-Semiperimeter Of Triangle )) to calculate the Area, Heron's formula (sometimes called Hero's formula), named after Hero of Alexandria, gives the area of a triangle when the length of all three sides are known. Area and is denoted by A symbol.

How to calculate Heron's formula using this online calculator? To use this online calculator for Heron's formula, enter Side A (a), Side B (b) and Semiperimeter Of Triangle (s) and hit the calculate button. Here is how the Heron's formula calculation can be explained with given input values -> 10.3923 = sqrt(6*(6-8)*(6-7)*(8+7-6)).

### FAQ

What is Heron's formula?
Heron's formula (sometimes called Hero's formula), named after Hero of Alexandria, gives the area of a triangle when the length of all three sides are known and is represented as A=sqrt(s*(s-a)*(s-b)*(a+b-s)) or Area=sqrt(Semiperimeter Of Triangle *(Semiperimeter Of Triangle -Side A)*(Semiperimeter Of Triangle -Side B)*(Side A+Side B-Semiperimeter Of Triangle )). Side A is an upright or sloping surface of a structure or object that is not the top or bottom and generally not the front or back, Side B is an upright or sloping surface of a structure or object that is not the top or bottom and generally not the front or back and The Semiperimeter Of the Triangle is half of the measurement of the perimeter of the triangle.
How to calculate Heron's formula?
Heron's formula (sometimes called Hero's formula), named after Hero of Alexandria, gives the area of a triangle when the length of all three sides are known is calculated using Area=sqrt(Semiperimeter Of Triangle *(Semiperimeter Of Triangle -Side A)*(Semiperimeter Of Triangle -Side B)*(Side A+Side B-Semiperimeter Of Triangle )). To calculate Heron's formula, you need Side A (a), Side B (b) and Semiperimeter Of Triangle (s). With our tool, you need to enter the respective value for Side A, Side B and Semiperimeter Of Triangle and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
