In this problem, we are given two values that denote the base and height of a parallelogram. Our task is to create a Program to find the Area of a Parallelogram in C++.
Parallelogram is a four side closed figure that has opposite sides equal and parallel to each other.

Let’s take an example to understand the problem,
Input
B = 20, H = 15
Output
300
Explanation
Area of parallelogram = B * H = 20 * 15 = 300
Solution Approach
To solve the problem, we will use the geometrical formula for area of parallelogram,
Area = base * height.
Program to illustrate the working of our solution,
Example
#include <iostream>
using namespace std;
float calcParallelogramArea(float B, float H){
return (B * H);
}
int main() {
float B = 20, H = 15;
cout<<"The area of parallelogram with base "<<B<<" and height "<<H<<" is
"<<calcParallelogramArea(B, H);
return 0;
}Output
The area of parallelogram with base 20 and height 15 is 300
