namespace TechStudyCSharp
{
    class Program
    {
        static void Main(string[] args)
        {

            double length, breadth, area;
            Console.WriteLine("Enter length of rectangle : ");
            length = Convert.ToDouble( Console.ReadLine());

            Console.WriteLine("Enter breadth of rectangle : ");
            breadth = Convert.ToDouble(Console.ReadLine());
            area = length * breadth;
            Console.WriteLine("\nArea of rectangle: " + area);          
            Console.ReadKey();
        }
