public class Triangle

{

public static void main(String args[])

{

double s1, s2, s3, s4, area;

Scanner s = new Scanner(System.in);

System.out.print("Enter the first side :");

s1 = s.nextDouble();

System.out.print("Enter the second side :");

s2 = s.nextDouble();

System.out.print("Enter the third side :");

s3 = s.nextDouble();

s4 = (s1 + s2 + s3 )/ 2 ;

area = Math.sqrt(s4 * (s4 - s1) * (s4 - s2) * (s4 - s3));

System.out.print("Area of Triangle is:"+area+" sq units");

}

}
