What is a hectare equivalent to in square measure?

A hectare is a metric unit commonly used in land measurement that is defined as being equal to 10,000 square meters. It can also be described as equivalent to 100 ares. The are is another metric unit of area, where one are is equal to 100 square meters. Therefore, since a hectare is made up of 100 ares, this makes the option stating that a hectare is equivalent to 100 ares correct.

The other options reflect different conversions and units that do not accurately represent the hectare's size. For instance, while a hectare is indeed larger than an acre, the correct conversion of a hectare in terms of ares clearly establishes its metric correlation. Thus, affirming its definition as 100 ares helps provide a clearer understanding of the unit’s scale in land measurement.
