How to align and adjust margins in the grid between rectangle in wpf?

Question

Hi Team

I have a rectangle and in between there is big space in between, want to minimize this space a bit by adjusting the margin of the grid so that it can be pushed a bit closer. How can i achieve such from this below code?

<Grid Background="White" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" Margin="0,29,0,10" Width="1766">
        <Rectangle HorizontalAlignment="Left" Height="257" Stroke="#FFCFCFD1" VerticalAlignment="Top" Width="260" Margin="14,104,0,0"/>

        <!---Ingredient Totals-->
