To determine how far the base of the ladder should be from the wall, you'd typically use the guideline known as the "4-to-1 rule." This rule recommends that for every 4 feet of height that the ladder reaches, the base should be 1 foot away from the wall.

In this scenario, if we assume that each rung of the ladder provides a standard height of approximately 1 foot, a 16-rung ladder would reach approximately 16 feet in height. According to the 4-to-1 rule, for a height of 16 feet, the base of the ladder should be set back 4 feet from the wall (16 feet divided by 4).

This guideline helps ensure stability and the safe use of ladders. Therefore, the recommendation to place the base of the ladder 4 feet from the wall ensures that it is positioned correctly to prevent accidents and ensure proper balance and support while in use.
