Assuming you mean "foot of the ladder": Sqrt(144 - 81) ie sqrt 63 = 7 feet 11¼ inches.
If you mean what you wrote then zero distance!
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.
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
Using Pythagoras' theorem the length of the ladder is 20.248 feet
12 feet.

62+82=36+64=100 and the squared route of 100 is 10
The slope is 4 (no units), and the ladder is 16.492 feet long. (rounded)
