• • Name: MilesToKilometers 
• • Parameter: o A double representing the miles distance 
• o A double representing the kilometers distance - this should be an "out" parameter 
  
• • Returns: Nothing

3.“OptionA” Method 

Create a method called “OptionA” that will print the conversion from pounds to kilograms by calling “PoundsToKilograms” method (defined in the item #4 below) starting at 200 pounds down to 50 pounds in decrements of 5. Show the result on a table in the console. 

4. “PoundsToKilograms” Method 

Create a method called “PoundsToKilograms” 

• • Name: PoundsToKilograms 
• • Parameter: A double representing the pounds 
• • Returns: A double representing the kilograms converted from pounds parameter 
• • Displays: Nothing 
• • Task: Calculates the conversion from pounds to kilograms. The converted kilogram is the returned value from the method. 

 Create a method called “OptionA” that will print the conversion from pounds to kilograms by calling “PoundsToKilograms” method (defined in the item #4 below) starting at 200 pounds down to 50 pounds in decrements of 5. Show the result on a table in the console. 

Write a program which requests a number between 1 and 50 from the user. It must repeatedly ask the user for a number until a valid number is entered. After receiving a valid number, the program must display all the even numbers smaller than that number.

12. Create a class named 'Rectangle' with two data members 'length' and 'breadth' and two functions to print the area and perimeter of the rectangle respectively. Its constructor having parameters for length and breadth is used to initialize the length and breadth of the rectangle. Let class 'Square' inherit the 'Rectangle' class with its constructor having a parameter for its side (suppose s) calling the constructor of its parent class. Print the area and perimeter of a rectangle and a square. C#
