A statue 8 meters high standing on the top of a tower 64 meters high, on the bank of a river, subtends at a point A on the opposite bank, directly facing the tower, the same angle as subtends at the same point A by man of height 2 meters standing at the base of the tower. Prove that the breadth of the river is `16sqrt(6)` meters.
