11. When an alidade and a plane table were set up over a point the elevation of the line of sight of the alidade was 406.29m. In order to determine the elevation of point M, the stepping method was used. The interval intercepted between the stadia hairs on a rod held on M was 1.95m. After the line of sight was depressed for five steps from the horizontal line of sight, the rod reading at the horizontal cross hair was 2.62m. Determine the elevation of point M.
