Question

write a java program for area and perimeter of right triangle

Answer 1

//RightTriangleAreaPerimeter.java
import java.util.Scanner;
public class RightTriangleAreaPerimeter {
    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);
        double base, height;
        System.out.print("Enter base of right angle triangle: ");
        base = scan.nextDouble();
        System.out.print("Enter height of right angle triangle: ");
        height = scan.nextDouble();

        double area = (base*height)/2;
        double perimeter = base+height+Math.sqrt(Math.pow(base,2)+Math.pow(height,2));

        System.out.println("Area = "+area);
        System.out.println("Perimeter = "+perimeter);
    }
}
