When properties are arranged in a township, what is created when four townships are combined?

When four townships are combined, the correct term for this larger area is a quadrant. A township itself is typically a six-mile by six-mile square, which contains 36 sections, each of which is one square mile. Therefore, when you take four adjacent townships (a two-by-two arrangement), you effectively create a larger area that can be described as a quadrant.

This terminology is commonly used in land measurement and surveying, especially in the context of the Public Land Survey System (PLSS) used in the United States. The term "quadrant" reflects the four divisions that contribute to this larger unit.

Other terms related to land measurement include "district" and "region," but these refer to larger or different delineations of land, not specifically the combination of townships. A section, on the other hand, is a much smaller unit than a township, so it would not be applicable in this context. Thus, the combination of four townships appropriately fits the description of creating a quadrant.
