Extracted text: 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.
