**Steve**, Tuesday, February 7, 2012 at 5:37pmI assume we're dealing with point-size worker and window, and that the ladder will just touch the window. try using that setup in real life!

Draw a diagram. You have a right triangle with sides 11 and 14

ladder must be sqrt(121+196) = 17.8 ft

The height of the fence is not relevant, as long as it is less than 10/11*14 = 12.72 ft. Any higher than that, and the ladder will rest on the fence, not against the building.
