    Modification of Class

    I need to modify the PerimeterCalc class so that a caller who has a square plot will be able to provide only one argument value for length and width (rather than two that are just the same) in the method invokation.

    I'm pretty sure I need to add another constructor but then what about the compute part?

    Class PerimeterCalc
    private PlotNumber
    private Length
    private Width
    private Perimeter
    public PerimeterCalc
    PlotNumber = "None"
    Length = 0.0
    Width = 0.0
    Perimeter = 0.0
    public PerimeterCalc (AnyPlot, AnyLength, AnyWidth)
    PlotNumber = AnyPlot
    Length = AnyLength
    Width = AnyWidth
    Perimeter = 0.0
    public GetMeasurements
    Input PlotNumber, Length, Width
    public ComputePerimeter
    Perimeter = (2.0 * Length) + (2.0 * Width)
    public ShowResults
    Display PlotNumber, Perimeter
    End Class
