The correct answer is - 33.97%.
Germany has a solid amount of arable land, and it is in the range of almost 34% (33.97% to be more precise) of the total land mass of the country. This land is heavily used, and Germany has a highly sophisticated and well organized production on this land, which enables it to both produce food for its own needs, and also for export in the other countries.
