On an aerial photograph of a triangular piece of land the lengths of the three sides are 4cm, 5cm and 7cm. If the shortest side of the actual piece of land is 360 meters, find the lengths of the other sides

  • physics - ,

    scale is 4cm:360m

    so, 5cm = (5/4)4cm : (5/4)360m = 450m
    and 7cm = (7/4)4cm : (7/4)360m = 630m
