Description

To calculate area of right angle triangle use formula.
Area of Right Angle Triangle = ½ (Base × Perpendicular)

C/C++

/* C Program to calculate right angle triangle */
//Save it as AreaRightAngleTriangle.c

#include<stdio.h>
int main(){

    float base, height, area;

    printf("Enter the base of triangle : ");
    scanf("%f",&base);

    printf("Enter the height of triangle : ");
    scanf("%f",&height);

    area = 0.5 * base * height;

    printf("The area of triangle : %.3f", area);

    return 0;
}

Input:
Enter the base of triangle : 2
Enter the height of triangle : 3

Output:
The area of triangle : 3.000

Java

/* Java Program to calculate right angle triangle */
//Save it as AreaRightAngleTriangle.java

import java.io.*;
import java.util.Scanner;

public class AreaRightAngleTriangle {

    public static void main(String[] args) {

            Scanner scanner = new Scanner(System.in);
        
            float base, height, area;

        System.out.println("Enter the base of triangle : ");
        base = scanner.nextFloat();

        System.out.println("Enter the height of triangle : ");
        height = scanner.nextFloat();

        area = (float) (0.5 * base * height);

        System.out.println("The area of triangle : " + area);
    }
}

Input:
Enter the base of triangle : 
2
Enter the height of triangle : 
3

Output:
The area of triangle : 3.0
