Using Pythagoras' theorem the length of the ladder is 20.248 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.
The proper distance of a ladder from a wall can be determined using the 4-to-1 rule: for every four feet of height you want to reach, the base of the ladder should be one foot away from the wall. This means if the top of the ladder is 12 feet high, it should be placed 3 feet away from the wall. This positioning helps ensure stability and safety while using the ladder. Always make sure the ladder is on a firm, level surface and positioned securely.
The height-to-base ratio for a ladder is determined by the relationship between the vertical height the ladder reaches and the distance from the base of the ladder to the wall or structure it leans against. A common guideline is to maintain a ratio of 4:1, meaning that for every four feet of height, the base should be one foot away from the wall. This helps ensure stability and safety while using the ladder.
Using Pythagoras' theorem the the foot of the ladder should be 12 feet away from the base of the building.

You lean a ladder that reaches to the top of a house. You want to measure how tall the house is, but you can't measure it. The base of the ladder is 6 feet away from the house and the ladder is 26 feet long. How tall is the house?
The best tip I've come to is that for every four feet of height you have to climb, move the base one foot away from the wall. Better still is to have someone foot the ladder, or to fasten the ladder with a rope, preferably near the top of the ladder to avoid the ladder sliding sideways.

Using Pythagoras' theorem it is 20 feet
To safely put a ladder on a sloped roof, use a ladder stabilizer or standoff to keep the ladder stable and prevent it from slipping. Make sure the ladder is long enough to extend at least 3 feet above the roof edge for proper support. Position the ladder at the correct angle, with the base of the ladder 1 foot away from the wall for every 4 feet of ladder height. Always have someone hold the ladder while you climb for added safety.
It will be a square shape and have an area of 169 square feet
