Yeah it's a bit of a weird way the article puts it. Measuring in square meters but then referencing basket ball courts which are almost nonexistent in Europe :). They should have used a football (but soccer, not the American kind) field. Though in that case I guess it will be a fairly small division of one too which makes it sound smaller than it is.
I honestly have no idea how big a basketball court is.
