Expert Answer:

 
 
By Pythagoras Theorem, we get
 
(Distance of the foot of the ladder from the wall)2= 152 - 122
                                                                        = 225 - 144
                                                                        = 81
 
→ Distance of the foot of the ladder from the wall = 9m
