A ladder is placed against a wall such that its foot is at a distance of 2.5 m from the wall and its top reaches a window 6 m above the ground. Find the length of the ladder.

Explanation

To find the length of the ladder placed against the wall, we can use the Pythagorean theorem. The situation can be visualized as a right triangle where:

- The distance from the wall to the foot of the ladder (base) is one leg of the triangle (BC).
- The height of the window above the ground (height) is the other leg of the triangle (AC).
- The length of the ladder (hypotenuse) is the side we want to find (AB).
