100 meters squared (7)

I believe the answer is:

hectare

(Other definitions for hectare that I've seen before include "Metric land area" , "Teacher of metric land measure" , "Metric measure of area" , "10,000 square metres" , "Metric unit of area" .)

I've seen this clue in The Wall Street Journal.
