Question

one of the world's largest stained glass windows is at kennedy International Airport in New York. It is a rectangle with a height to length ratio of 2 to 25. If the window is 24 feet high how long is it?

Answer 1

This is just a basic proportion problem. we are comparing the RATIO of the height to length. so the ratio would b 
height    height
--------     -------
length    length  . the numbers it gives us are 2 to 25 so substitute those in on the same side since they go together. 
24     2
---   ---
x    25. they also told is that the height of the window is 24 so put that on the top too because its length. then just cross multiply to get 2x=600 
then divide and get the answer of x=300
