Step-by-step explanation:

Suppose that AB is the ladder, B is the window and CB is the building. Then, triangle ABC is a right triangle with right-angle at C.

By pythagoras theoram, we have

∴ AB2=AC2+BC2

⇒ 252=AC2+202

⇒ AC2=625−400=225

⇒ AC=225m=15m

Hence, the foot of the ladder is at a distance 15m from the building.
