Pythagoras says . The ladder itself is c, and the distance from the foot of the ladder to the base of the vertical wall is either a or b, as you please, so:

So the ladder reaches meters up the wall. Roughly 12.6 meters.

By the way, that is a HUGE ladder, over 42 and a half feet long. It would reach to the 4th floor of most multi-story buildings.
