I believe it would be A, or B. I say this because I took 12 - 3 or a possible answer, and the Ultimate height as a possible answer. Sorry I can't give a better description, hopefully you get it right! Sorry lots

I guess they tried to trip you up with the base part of the question, it was irrelevant to the whole of the problem, I can't believe I fell for that one!

for future reference:

this is a classic pythagorean theorem problem, where the ladder is the hypotenuse, the distance between the ladder and the wall is the base, and the wall itself is another leg.

x^2 + 3^2 = 12^2, solving for x gets you approx. x = 11.6 feet
