Which unit measures land area as equivalent to 10,000 square meters?

The correct answer is the hectare, which is a metric unit of area measurement that is equivalent to 10,000 square meters. This unit is commonly used in land planning and agricultural contexts because it provides a convenient scale for larger areas of land. The hectare is widely recognized and facilitates international communication regarding land area, especially in fields such as environmental science and land management.

In comparison, the other units measure land area differently; for instance, an acre is equivalent to approximately 4,046.86 square meters, while a square foot and a square yard refer to much smaller areas (1 square foot is 0.0929 square meters and 1 square yard is 0.8361 square meters). Thus, while all these units measure area, only the hectare is defined as 10,000 square meters, distinguishing it within the context of larger land areas.
