Find the Area of a Triangle Given Three Sides – Heron’s Formula

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:


Area of triangle : 7.826237921249264 sq uni
