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
