Hmmm ?
800 ha = 800 x 100 x 100 m = 8 km x 1 km.
I know that everything is bigger in the US, but your football players
should be real sportsmen !
May be you know that the French decree of 1 Aug. 1793 defined the are
as a square of 100 by 100 m. We can derive derive that an hectare
(1793) was a square of 1 km by 1 km. 800 ha would mean a field of
some 9 by 9 km !
The are = a square of 10 x 10 m was introduced by the decree of 7 April 1795.
