Hi Friend,

We are providing you a code that will calculate the area of triangle having base and height.

import java.util.*;

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

System.out.print("Enter base (in cm): ");
double b = scanner.nextDouble();

System.out.print("Enter height (in cm): ");
double h = scanner.nextDouble();

double area=b*h*1/2;
System.out.println("Area of Triangle =" +area);
}
}
Thanks
