Task: Write a Java Program Area of Triangle by Three Sides.

### The Source Code of Java Program Area of Triangle by Three Sides

/* * Write a Java program to find the area of a triangle when lengths of three sides are given. */ package trianglearea; import java.util.Scanner; /** * @author www.EasyCodebook.com */ public class TriangleArea { public static void main(String[] args) { double a,b,c, s, area; Scanner input=new Scanner(System.in); System.out.print("Enter length of side1:"); a=input.nextDouble(); System.out.print("Enter length of side2:"); b=input.nextDouble(); System.out.print("Enter length of side3:"); c=input.nextDouble(); s = (a+b+c)/2.0; area= Math.sqrt(s*(s-a)*(s-b)*(s-c)); System.out.println("Area of Triangle with Heron Formula:"+area); } }

**Output of Java Program Area of Triangle by Three Sides:**

Enter length of side1:5 Enter length of side2:5 Enter length of side3:5 Area of Triangle with Heron Formula:10.825317547305483
