Using Pythagoras' theorem the length of the ladder is 20.248 feet
Regard the ladder as the hypotenuse and the distance from the wall as one leg of a right angled triangle. Then, 262 = 102 + H2 : where H is the height reached up the wall by the ladder. H2 = 676 - 100 = 576 : H = √576 = 24
12 feet.
For a working height of 12 feet, the ladder should be placed at a base distance of approximately 3 feet away from the wall for every 4 feet of ladder height. This means the base of the ladder should be about 9 feet from the wall. Additionally, ensure that the ladder is on stable ground and that the top is securely positioned against the surface to prevent slipping. Always follow the manufacturer's guidelines for specific ladder types.

It depends if you want the ladder to overhang or to be set under but I would say 2 feet or 2/3 of a meter
To safely install a ladder on stairs to reach high places, you can use a ladder stabilizer or standoff to ensure stability. Make sure the ladder is the right height and angle for the stairs, and always have someone hold the ladder while you climb. Additionally, use non-slip feet and secure the ladder at the top to prevent it from slipping.
Hypotenuse = 20/sin580 = 23.58356807 Length of ladder: rounded to 23.584 feet
Assuming it is a two section ladder then it must therefore have a minimum length of 28 feet.
