A tree has a shadow that is 9 feet long. Otis is 4 feet tall, and he is standing next to the tree. Otis has a shadow that is 4.5 feet long.

8 ft

Step-by-step explanation:

We can use ratios to solve

tree                          Otis

 =

tree shadow          Otis shadow

tree                   4 ft

=

9 ft                   4.5 ft

Using cross products

4.5 tree = 4* 9

4.5 tree = 36

Divide each side by 4.5

tree = 36/4.5

tree =8

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.
