# Program to find the Area of a Pentagon in C++

In this problem, we are given a number n that denotes that side of the pentagon. Our task is to create a program to find the Area of a Pentagon in C++.

Pentagon is a five-sided geometric figure.

**Regular pentagon** is a pentagon with all five sides and angles equal.

**Let’s take an example to understand the problem,**

## Input

a = 7

## Output

84.3

**Program to illustrate the working of our solution,**

## Example

#include <iostream> using namespace std; float calcpentagonArea(int a){ return ( ((6.8819)*a*a)/4); } int main() { int a = 7; cout<<"The area of regular pentagon of side "<<a<<" is"<<calcpentagonArea(a); return 0; }

## Output

The area of regular pentagon of side 7 is 84.3033
