Write a Rectangle class that has the following fields: Length (L): a double Width (W): a double The class should have the following functions: Constructor: accepts the length (L) and the width (W) of a rectangle as arguments. Constructor: does not take any parameters and initializes the length(L) and width(W) to zero. A function called getArea which returns the area of the rectangle. A function called getPerimeter which returns the perimeter of the rectangle.             {note:  The area of a rectangle = L*W,  and its perimeter = 2*(L+W) }   Then, write a program to ask the user to enter the length and width of a rectangle, and then use the above class to calculate and print the area and perimeter of the rectangle.

Write a Rectangle class that has the following fields:

  • Length (L): a double
  • Width (W): a double

The class should have the following functions:

  • Constructor: accepts the length (L) and the width (W) of a rectangle as arguments.
  • Constructor: does not take any parameters and initializes the length(L) and width(W) to zero.
  • A function called getArea which returns the area of the rectangle.
  • A function called getPerimeter which returns the perimeter of the rectangle.

 

          {note:  The area of a rectangle = L*W,  and its perimeter = 2*(L+W) }

 

Then, write a program to ask the user to enter the length and width of a rectangle, and then use the above class to calculate and print the area and perimeter of the rectangle.
