What measurement describes a section in land surveying terms?

A section in land surveying terms is defined as an area of land that measures 640 acres. This measurement is part of the Public Land Survey System (PLSS) used in the United States, which divides land into townships, each comprising 36 sections. Each section then is a square mile, which can be broken down into smaller lots for various uses. Therefore, when identifying sections of land, the measurement of 640 acres is significant and standard in both legal and practical applications for property and resource management. The other measurements provided do not correspond to the standardized size of a section within this surveying system, making 640 acres the definitive answer.
