What is a polygon?

A polygon is any 2-dimensional shape formed with straight lines. Triangles, quadrilateral, pentagon, and hexagon are all examples of polygons.
A regular polygon is a polygon in which all sides of the polygon are of equal length. We have a mathematical formula so that the area of ​​a regular polygon can be calculated. Area = (ln * ln * n / 4 * (tan (180 / n)) Where ln = Length of the edge of the polygon Number of sides in a polygon = tan = touch function in degrees

Java Program to Print the Area of Triangle

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

public class Triangle{

public static void main(String []args)
{
Scanner ob=new Scanner(System.in);
int l,h;
System.out.println("Enter the length of Traingle: ");
l=ob.nextInt();
System.out.println("Enter the height of Traingle: ");
h=ob.nextInt();

double t=0.5*l*h;
System.out.println("Area of Triangle: "+t);

}
}

Output:
