A way that a quick mental calculation estimate could have been done is to remember that a meter is a little longer than a yard, and thus a little longer than 3 feet. Thus a square meter would be a little more than 9 square feet. One square foot is thus about 1/9 th of a square meter, thus, one square foot equals about 0.1 square meters.
