I should do it in green cause its the Green Monster - so the wall is 11.3 meters high but the actual displacement, let me just draw this as a wall, but the actual displacement doesn't have to be 11.3 meters it has to be, if we're starting at 1 meter altitude, we have to get 10.3 more meters in altitude, so the displacement has to be 10.3 meters in the vertical direction.
