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

Leave a Comment / By Yogesh / August 20, 2016

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):

Enter base of triangle : 6
Enter height of triangle : 12
Area of triangle is : 36.00
 
Enter base of triangle : 10
Enter height of triangle : 20
Area of triangle is : 100.00
