Answer:

9.2 feet

Step-by-step explanation:

This is a Pythagorean theorem question

The ladder is the hypotenuse or c

the distance from the wall is a leg or a

and the wall is the other leg or b

a² + b² = c²

6² + b² = 11²

36  + b² = 121

-36             -36

          b² = 85

         √        √

          b = √85

           b = 9.2 feet
