Question

write a java program to input three sides of a triangle, evaluate and print the area of triangle using the area is= √s(s-a)(s-b)(s-c) where s=a+b+c/2 and a,b,c are the three sides​

Answer 1

Answer:

// Java Program to find Area of Triangle and Perimeter of a Triangle

package Area;

import java.util.Scanner;

public class AreaOfTriangle {

private static Scanner sc;

public static void main(String[] args) {

 double a, b, c, Perimeter, s, Area;

 sc = new Scanner(System.in);

 

 System.out.println("\n Please Enter Three sides of triangle: ");

 a = sc.nextDouble();

 b = sc.nextDouble();

 c = sc.nextDouble();

 Perimeter = a + b + c;

 s = (a + b + c)/2; // Perimeter/2

 Area = Math.sqrt(s*(s-a)*(s-b)*(s-c));

 System.out.format("\n The Perimeter of Traiangle = %.2f\n", Perimeter);

 System.out.format("\n The Semi Perimeter of Traiangle = %.2f\n",s);

 System.out.format("\n The Area of triangle = %.2f\n",Area);

}

}
