What is the nominal width of the "Regular" East half of Section 6?

The nominal width of the "Regular" East half of Section 6 is 40 Chains. In the Public Land Survey System (PLSS), each section is typically one square mile, which equates to 640 acres. When sections are divided into halves, like the East half, the total area still remains at 320 acres, just split evenly.

Since one mile is equivalent to 80 chains (with 1 chain measuring 66 feet), the East half of a section measures 1 mile in length. Thus, when discussing width in terms of chains, the East half, which represents half of the section's width, measures 40 chains across because it covers half the width of the 80 chains that make up a full mile.

In the context of the multiple-choice answers, the 40 Chains is the standard measure reflecting half the total width of a section in the PLSS, specifically for Oklahoma, aligning with land survey practices.
