Answer:
8 feet
Step-by-step explanation:
First I used the proportion method to set up the numbers. I used x for the height of the tree.
x/9 = 4/4.5
Notice that the height of the tree and Otis's height are both the numerators (top numbers) of the fractions. Also, the height of the tree and the length of its shadow are one fraction, and Otis's height and his length are another separate fraction.
Same with the length of the tree's shadow and the length of Otis's shadow. They are both denominators (bottom numbers) of the fractions.
Next, I did 4 times 9 and got 36. Then I did 36 divided by 4.5 and got 8.
You're welcome! :)
