Two consecutive photographs were taken with a camera of focal length 37.5 cm, ata height of 7200 m. The overlap was exactly half and the prints were 22.5 cm X225 cm. The height was same for both the exposures and the aircraft flew on even peel with no drift. The ground was flat at approximately 2500 m above m.s.. Determine the scale of the photograph and length of the air base.
