Answer:

26.93 feet

Step-by-step explanation:

when the ladders rests against a house, a right angled triangle would be formed.

The ladder would be the hypotenuse

the building would be the height

the floor would be the base. we are to determine the base

Given Pythagoras theorem

a² + b² = c²

where c is the hypotenuse

25²+ 10² = c

c² = 100 + 625

c² = 725

c = √725

c = 26.93 feet
