Program to compute the area and perimeter of Heptagon

Problem statement:-  Program to compute the area and perimeter of the Heptagon.

Formula:

Area Of Heptagon(A):

The above equation is approximately equal to

A = 3.634a2 

where a=side length of the Heptagon

Perimeter of Heptagon(P):

P

=

7a

 Data requirement:-

   Input Data:- a

  Output Data:- area, perimeter

Program in C

Here is the source code of the C Program to compute the area and perimeter of the Heptagon.

Code:

#include<stdio.h>
#include<math.h>
int main()
{
    printf("Enter the length of the side:");
    int a;
    scanf("%d",&a);
    double area=3.634*pow(a,2);
    int perimeter=(7*a);
    printf("Area of the Heptagon = %0.2lf\n",area);
    printf("Perimeter of the Heptagon = %d",perimeter);
}

Input/Output:

Enter the length of the side:5
Area of the Heptagon = 90.85
Perimeter of the Heptagon = 35
