Using proportioanl relationship, the height of a tree that cast a shadow of 27 feet is 30 feet.
What is a proportional relationship?
Proportional relationship are relationships between two variables where their ratios are equivalent.
There heights of your friend and the tree and there shadows from a proportional relationship .
Therefore,
height of your friend = 5 ft
length of shadow of your friend = 4.5 ft
Height of the tree = x
length of the shadow of the tree = 27 ft
Hence,
5 / x = 4.5 / 27
cross multiply
27 × 5 = 4.5 × x
135 = 4.5x
x = 135 / 4.5
x = 30
