Elementary Programming; Exercise No. 14

Write a program that prompts the user to enter the side of a hexagon and displays its area. The formula for computing the area of a hexagon is:

 where s is the length of a side.

Solution:

public static void main(String[] args) {
   Scanner s = new Scanner(System.in);
   double side, area;

   System.out.print("Enter the side:");
   side = s.nextDouble();

   area = ((3 * Math.pow(3, 0.5) / 2)) * Math.pow(side, 2);

   System.out.print("The area of the hexagon is " + area);
}
