Question

write a java program to enter the perimeter of an equilateral triangle and find its side and area

Answer 1

import java.util.*;

public class Side_Area

{

public static void main(String args[])

{

Scanner in = new Scanner(System.in);

int p,s,a;

System.out.println("Enter the perimeter of the triangle");

p=in.nextInt();

s=p/3;

a=Math.sqrt(3*s*s/4);

System.out.println("The side is"+s);

System.out.println("The area is"+a);

}

}

Answer 2

Import java.util.*;

public class Area

{

public static void main(String args[])

{

Scanner in=new Scanner(System.in);

double m,n,o;

System.out.println("Enter the perimeter of the triangle");

m=in.nextDouble();

n=m/3;

o=Math.sqrt(3)*(n*n)/4;

System.out.println("Display the side"+n);

System.out.println("Display the area"+o);

}

}
