Given the number of sides ‘n’ and the length of side ‘s’ of a regular polygon, the task is to find out the Perimeter of this polygon.
Examples:
Input: n = 7, s = 10 Output: Perimeter : 70 Since the sides are 7, Hence the given polygon is Heptagon. Therefore. Perimeter = 7*10 = 70 Input: n = 5, s = 2.5 Output: Perimeter : 12.5 Since the sides are 5, Hence the given polygon is Pentagon. Therefore. Perimeter = 5*2.5 = 12.5
Approach: In geometry, a regular polygon is a closed figure with all sides equal. It is a two-dimensional figure.
Perimeter of a Regular Polygon = Number of sides * Length of each side
Below is the implementation of the above approach:
C++
// C++ program to find the // perimeter of a regular polygon #include <iostream> using namespace std;
// Function to calculate the perimeter float Perimeter( float s, int n)
{ float perimeter = 1;
// Calculate Perimeter
perimeter = n * s;
return perimeter;
} // driver code int main()
{ // Get the number of sides
int n = 5;
// Get the length of side
float s = 2.5, peri;
// find perimeter
peri = Perimeter(s, n);
cout << "Perimeter of Regular Polygon"
<< " with " << n << " sides of length "
<< s << " = " << peri << endl;
return 0;
} |
C
// C program to find the // perimeter of a regular polygon #include <stdio.h> // Function to calculate the perimeter float Perimeter( float s, int n)
{ float perimeter = 1;
// Calculate Perimeter
perimeter = n * s;
return perimeter;
} // driver code int main()
{ // Get the number of sides
int n = 5;
// Get the length of side
float s = 2.5, peri;
// find perimeter
peri = Perimeter(s, n);
printf ( "Perimeter of Regular Polygon\n"
" with %d sides of length %f = %f\n" ,
n, s, peri);
return 0;
} |
Java
// Java program to find the // perimeter of a regular polygon class GFG {
// Function to calculate the perimeter
static double Perimeter( double s, int n)
{
double perimeter = 1 ;
// Calculate Perimeter
perimeter = n * s;
return perimeter;
}
// Driver method
public static void main(String[] args)
{
// Get the number of sides
int n = 5 ;
// Get the length of side
double s = 2.5 , peri;
// find perimeter
peri = Perimeter(s, n);
System.out.println( "Perimeter of Regular Polygon"
+ " with " + n + " sides of length "
+ s + " = " + peri);
}

Output:
Perimeter of Regular Polygon with 5 sides of length 2.500000 = 12.500000
Time Complexity: O(1), since there is no loop or recursion.
Auxiliary Space: O(1), since no extra space has been taken.
