Java help needed! Consider the following statement.

double triangleArea = someObject. calcTriangleArea(14)

Write an instance method that calculates the area of a triangle using a class constant of 2 feet for the base of a triangle. The value passed to the method represents the height of the triangle in feet.

import java.util.Scanner;

class AreaTriangleDemo {

  public static void main(String args[]) {    

     Scanner scanner = new Scanner(System.in);

     System.out.println("Enter the width of the Triangle:");

     double base = scanner.nextDouble();

     System.out.println("Enter the height of the Triangle:");

     double height = scanner.nextDouble();

     //Area = (width*height)/2

     double area = (base* height)/2;

     System.out.println("Area of Triangle is: " + area);      

  }

}

Output:

Enter the width of the Triangle:

2

Enter the height of the Triangle:

2

Area of Triangle is: 2.0

Program 2:

class AreaTriangleDemo2 {

  public static void main(String args[]) {    

     double base = 20.0;

     double height = 110.5;

     double area = (base* height)/2;

     System.out.println("Area of Triangle is: " + area);      

   }

}

Output:

Area of Triangle is: 1105.0
