JavaBeginner

Java

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);

        System.out.print("Enter base: ");
        double base = sc.nextDouble();
        System.out.print("Enter height: ");
        double height = sc.nextDouble();

        double area = 0.5 * base * height;
        System.out.println("Area of triangle = " + area);

        sc.close();
    }
}

Output

Enter base: 10
Enter height: 5
Area of triangle = 25.0

We use the formula area = 1/2 × base × height.
