How many acres are in one section of land?

One section of land, as defined in the U.S. Public Land Survey System, contains 640 acres. This measure is part of a larger system that divides land into townships and sections to facilitate the sale and distribution of land. In this system, a township is 6 miles by 6 miles, which equals 36 square miles. Each section within a township is 1 mile by 1 mile, which is equal to 640 acres (1 square mile = 640 acres).

This knowledge is important for understanding land management, agricultural practices, and property ownership, particularly in rural and agricultural contexts. The other choices reflect different measurements that are not equivalent to what constitutes a section of land, which is specifically set at 640 acres.
