Question 276622: Hello,
The question is... We are trying to measure the height of a building. We have a 1-meter long stick. When we set it on the ground, its shadow is 3 meters long. When we measure the shadow of the building, it is 57 meters long. How high is the building?

I am thinking the answer is 40 m but, I am not sure. I would be grateful for any help available.

You can put this solution on YOUR website! We are trying to measure the height of a building.
We have a 1-meter long stick. When we set it on the ground, its shadow is 3 meters long. When we measure the shadow of the building, it is 57 meters long. How high is the building?
------------------
Proportion:
height/shadow = height/shadow
---
x/57 = 1/3
---
Cross-multiply
3x = 57
x = 19 meters (the height of the building)
