A palm tree stands on the bank of a river. A post is fixed in the earth on the other bank just opposite to the palm tree. On moving ` 7sqrt(3)` metres from the post along the bank, it is found that the tree makes an angle of `60^(@)` at that point with respect to this bank. Find the width of the river.
