How can I calculate the distance between the sides of a rectangle?

Question

In this example:

private void pictureBox1_MouseUp(object sender, MouseEventArgs e)
{
    label10.Text = ((n - 1) * 4).ToString();
    _mrect = new Rectangle(Math.Min(RectStartPoint.X, point.X), Math.Min(RectStartPoint.Y, point.Y),
                                Math.Abs(RectStartPoint.X - point.X), Math.Abs(RectStartPoint.Y - point.Y));
}

_mrect is:

X = 125
Y = 144
Width = 250 
Height = 169

I want to find the distance between the left edge of the rectangle to the right edge. And the distance between the top edge to the bottom edge.
