/* Add your code for the following methods, to produce the sample output shown below: 

    getLength - This method should ask the user to enter the rectangle's length, and then return that value as a double.
    getWidth - This method should ask the user to enter the rectangle's width, and then return that value as a double.
    getArea - This method should accept the rectangle's length and width as arguments, and return the rectangle's area. The area is calculated by multiplying the length by the width.
    displayData - This method should accept the rectangle's length, width, and area as arguments, and display them in an appropriate message on the screen, formatted with 1 digit after the decimal point.

/* Sample Output:

[cpersiko@fog cs111a]$ java RectangleArea
Enter the rectangle's length: 5
Enter the rectangle's width: 10
Length  = 5.0 
Width = 10.0 
Area  = 50.0
[cpersiko@fog cs111a]$ java RectangleArea
Enter the rectangle's length: 1.25
Enter the rectangle's width: 3.25
Length  = 1.3 
Width = 3.3 
Area  = 4.1
