The diameter of a log cannot be determined from its length.

Assuming it is a two section ladder then it must therefore have a minimum length of 28 feet.

That probably refers to the ratio between the length of the ladder, and the distance at which you place the bottom part of the ladder from the wall. If this distance is too short, you have the risk of the ladder falling backwards.
The length of a square is not determined by a formula, it is determined by measuring the square.
length = volume/cross-section
