Find area of triangle using base & height in java (example)

• Given base & height of triangle, calculate the area of triangle.
  • Area of triangle =  0.5 * base  * height.
• e.g Given base = 4 and height 6.
  • Area of triangle = 0.5 * 4 * 6 = 12.

Program: calculate area of triangle using height & base in java (example)

package org.learn;

import java.util.Scanner;

public class AreaOfTriangle {

 public static void main(String[] args) {
  try (Scanner scanner = new Scanner(System.in)) {
   System.out.printf("1. Enter base of triangle : ");
   double base = scanner.nextDouble();  
   
   System.out.printf("2. Enter height of triangle : ");
   double height = scanner.nextDouble();   
    
   //Area of triangle is 0.5 * (base * height) 
   double area = 0.5 * base * height;
   //Print area up to two precision
   System.out.printf("3. Area of triangle is : %4.2f",area);
  }
 }
}

Output: find area of triangle using base & height in java (example):

1. Enter base of triangle : 6
2. Enter height of triangle : 12
3. Area of triangle is : 36.00

1. Enter base of triangle : 10
2. Enter height of triangle : 20
3. Area of triangle is : 100.00
