Using Pythagoras' theorem the length of the ladder is 20.248 feet
step ladder
Extension Ladder
To determine the minimal length of a ladder needed to reach a landing nine feet above the adjacent floor, we can use the Pythagorean theorem. Assuming the ladder is positioned at a safe angle (typically around 75 degrees), the minimal length can be calculated. For a height of 9 feet, a ladder length of approximately 10.2 feet would be required when factoring in the angle for safe use. Always ensure the ladder is placed securely and follows safety guidelines.
10 feet, and it is at a very dangerous angle.
you pick it, and walk backward, so you don't walk through the ladder, you will still be lucky!

Meters, centimeters, or millimeters. Take your pick.
The length of a ladder is typically measured by its height rather than the number of rungs. A 14-rung ladder could vary in length depending on the size and spacing of the rungs, but generally, a 14-foot ladder is a common size for household use.
The length of a step ladder is its height. An eight foot step ladder is 8' long.
