Heron's formula
Finds the area of a triangle from the lengths of its three sides alone.
Equation
S = sqrt(s(s-a)(s-b)(s-c)), s = (a+b+c)/2
Variables
| S | area of the triangle (m²) |
|---|---|
| a | Length of side a (m) |
| b | Length of side b (m) |
| c | Length of side c (m) |
| s | semiperimeter (m) |
