What is a hectare?

A new renewable energy project was proposed in New England, which will produce electricity by harnessing the power of the sun. There is a 20-hectare solar energy park proposal for a farmland in Lincolnshire. The actual panels will take up just 19.5 hectares and that the land underneath will provide significant sheep grazing.

20 hectares= 2,152,782ft^2

1 hectare= 107,639ft^2
