Tutoring science, the metric system may arise. The tutor mentions the definition of a hectare.
a square unit spanning 10000m2.
A hectare can be pictured an as area 100m wide by 100m long.
Another way to imagine a hectare is that it’s 2.47 acres.
Perhaps my favourite way to relate a hectare is that the grassy area enclosed by a school track (400m) is 1.12 hectares.
