Question

A man is 6 feet tall. To find the height of a tree, the shadow of the man and the shadow of the tree were measured. The length of the man's shadow was 4 feet 6 inches. The length of the tree's shadow was 12 feet. What is the height of the tree?
9 ft
15.7 ft
16 ft
32 ft

Answer 1

Answer:

16 ft

Step-by-step explanation:

Answer 2

The answer is 16 ft because 6 ft tall over 4 feet 6 inches (4.5) is equal to x (tree's height) over 12 ft. You cross multiple and get 72 = 4.5x then you take 72 and divide by 4.5 to get the tree's height

$\frac{6}{4.5} = \frac{x}{12}$
