Program to find the area of a pentagon

The Pentagon is defined as a polygon which has 5 sides that are equal. The 5 angles present in the Pentagon are also equal. A Pentagon can be divided into 5 similar triangles. The measurement of each interior angle in a regular pentagon 108 degrees.

The Formula to calculate the area of the Pentagon is,

Where

s is the side of the Pentagon.
a is the apothem length.

Algorithm

Create variables ‘s’ and ‘a’ and assign its value as 10 and 6.
Create variable area_pentagon equals to (5/2)X(s)X(a) as per the formula of calculating the area of the Pentagon.

Complexity

O(1)

Solution

C Program

  #include   int main()  {     int s=13;     int a=5;     float area_pentagon=(5.0/2.0)*s*a;     printf(“Area of the pentagon=%0.1f”,area_pentagon);  }  

Output:

Area of the pentagon=162.5

PHP Program

  <?php       $s=13;     $a=5;     $area_pentagon=(5/2)*$s*$a;      echo “Area of the pentagon=”;      echo $area_pentagon;  ?>    

Output:

Area of the pentagon=162.5

Java Program

  public class pentagon{      public static void main(String args[])      {     int s=13;     int a=5;     float area_pentagon=(float)(5.0/2.0)*s*a;          System.out.println(“Area of the pentagon=”+area_pentagon);       }  }  

Output:

Area of the pentagon=162.5

C# Program

  using System;  public class Program  {  public static void Main()  {  int s=13;  int a=5;    double area_pentagon=(double)(5.0/2.0)*s*a;         Console.WriteLine(“Area of the pentagon=”+area_pentagon);  }  }  

Output:

Area of the pentagon=162.5

Python Program

  s=13  a=5  area_pentagon=(5.0/2.0)*s*a  print(“Area of the pentagon=”+str(area_pentagon))  

Output:

Area of the pentagon=162.5
