Let’s find out a simple and easy way to code these formula.

Practical Implementation:

using System;

namespace patternProblem.Formula
{
class Formula4     //perimeter and area of rectangle
{
static void Main(string[] args)
{
Console.Write("Enter length: ");
double area = 0.0, perimeter = 0.0;

perimeter = 2 * (length + breadth);

Console.WriteLine("Perimeter of rectangle: {0}", perimeter);
Console.WriteLine("Area of rectangle: {0}", area);

}
}
}

Output:
The input length here is 5 and breadth here is 3. So, based on the rectangle formula. The output is shown below:

Enter length: 5
Perimeter of rectangle: 16
Area of rectangle: 15
