Objective – Given three sides of triangle, write a program to find the area of a triangle.
Heron’s Formula for finding area of triangle:
- First find the semi parameter of a triangle using formula, s= (a+b+c)/2 where a, b, c are three sides of triangle and s will the semi parameter.
- Then use the below formula to get the area of triangle.
- Area = √s(s-a)(s-b)(s-c)

| public class AreaOfTriangle { | |
| public static void area(double a, double b, double c){ | |

| double s = (a + b + c)/2; | |
| //find the area of triangle | |
| double area = Math.sqrt(s*(s–a)*(s–b)*(s–c)); | |
| System.out.println("Area of triangle : " + area + " sq unit"); | |

| public static void main(String[] args) { | |
| double a = 3.5; | |
| double b = 4.5; | |
| double c = 6.0; | |
| area(a,b,c); | |

Output:
Area of triangle : 7.826237921249264 sq uni
