public interface IStrapDimensions
{
    double Length { get; }
    double Width { get; }
 
    double CalcArea();
}

    private double length;
    public double Length
    {

    }
 
    private double width;
    public double Width
    {

    }
 
    public double CalcArea()
    {
        return Length * Width;
    }
 
    public DogCollar(double len, double wid)
    {
        length = len;
        width = wid;
    }
