**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)**

**Java Code**:

public class AreaOfTriangle { | |

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

//get the semi parameter | |

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
