You can write c# code to set the next rectangle based on previous one. Modified code will be:

C#

static double prevLoc = 0;
void b_Click(object sender, RoutedEventArgs e)
{
    //throw new NotImplementedException();

    Rectangle rectangle = new Rectangle();
    rectangle.Fill = new SolidColorBrush(Colors.Cyan);
    rectangle.Width = 200;
    rectangle.Height = 100;
    rectangle.SetValue(Canvas.LeftProperty, prevLoc);
    prevLoc += 25;
    LayoutRoot.Children.Add(rectangle);

}
