I think it is not 17 feet it is 7 feet.
Fiirst we need to find at what height ladder is placed.
Let BC is ladder and AC is Building with foot at C.
Now as given AB = 25
BC = 7
Using Pythagorous Theroem
(AB2) = (BC)2 + (AC)2
=> 625 = 49 + (AC)2
=> (AC)2 = 576
=> AC = 24
It slips down 4 feet it means its top is at 20 feet height
So Now
AC = 20
AB = 25
then again Using theorem
(BC)2 = 625 - 400
(BC)2 = 225
BC = 15
it mean it slips 8 feet.
