An alien is 5 feet tall. His shadow is 8 feet long. At the same time of day, a trees shadow is 32 feet long. What is the height of the tree?

Answer 1

We can set up a proportion to solve this problem. Let's call the height of the tree "x". According to the given information, we have:

Alien's height / Alien's shadow = Tree's height / Tree's shadow.

Substituting the given values, we get:

5 feet / 8 feet = x / 32 feet.

To solve for x, we cross-multiply:

5 feet * 32 feet = 8 feet * x.

160 feet = 8 feet * x.

Dividing both sides of the equation by 8 feet, we find:

160 feet / 8 feet = x.

20 feet = x.

Therefore, the height of the tree is 20 feet.
