what is a hectare?

A Hectare is a metric unit of land area.

1 hectare => 10,000 m²

Visually, we could imagine this is a square 100m by 100m.

1 ha | 10 daa (decares)

 | 100 a (ares)

 | 0.01 km^2 (square kilometers)

 | 10000 m^2 (square meters)

 | 2.471 acres

 | 0.003861 mi^2 (square miles)

 | 107639 ft^2 (square feet)

The hectare is a non-SI metric unit of area equal to a square with 100-metre sides (1 hm^2), or 10,000 m^2, and is primarily used in the measurement of land.

a metric unit of square measure, equal to 100 ares (2.471 acres or 10,000 square metres).

now these are the questions that need to be asked
