Walls are perpendicular to floors. So there is a 90 degree angle there. This means that the ladder, the floor (between the wall and the ladder) and the wall (between the floor and the ladder) form a right triangle with the ladder as the hypotenuse and the floor and the wall forming the legs.

Use the equation for the Pythagorean Theorem to solve this problem.
