Another problem with methods

Create a console-based application named Area. Include
three overloaded methods that compute the area of a
rectangle when two dimensions are passed to it. One
method takes two integers as parameters, one takes two
doubles, and the third takes an integer and a double.
Write a Main() method that demonstrates each method
works correctly.

I have done this

  Console.WriteLine("Enter the hight of the rectangle:");
  double stNumber = Convert.ToDouble(Console.ReadLine());
  Console.WriteLine("Enter the hight of the rectangle:");
  double ndNumber = Convert.ToDouble(Console.ReadLine());
  AreaOfRectangle(ref stNumber, ref ndNumber);
 
 
  }
  static void AreaOfRectangle(ref int length,ref int width)
  {
  int area;
  area = length * width;
  Console.WriteLine("The area of rectangle is {0}", area);
  }
  static void AreaOfRectangle(ref double length,ref double width)
  {
  double area;
  area = length * width;
  Console.WriteLine("The area of rectangle is {0}", area);
  }
  static void AreaOfRectangle(ref int length,ref double width)
  {
  double area;
  area = length * width;
  Console.WriteLine("The area of rectangle is {0}", area);
  }

You think there's better way to do it?
