Question

In estimating the height of a tree, the following measurements were recorded:
Height of the rod = 180cm.
Length of the shadow of the rod = 116cm
Length of the shadow of the tree = 420cm
Calculate the height of the tree.

Answer 1

Height of tree = Length of the shadow of tree
Height of rod      length of the shadow of rod
Height of tree = 420
    180                      116
Height of tree = 420 × 180
                               116
                     = 420 × 180
                             116           
                    = 651.72cm or 6.517m
