<span>Inno: use the square root of 9 and the square root of 16
10 is between the perfect squares
3^2 = 9
and
4^2 = 16
Rosa's solution of 9 and 25 uses perfect squares but the wider range leaves more room for error. Roberto's as well with the added problem that 90 is not a perfect square and calculating that square root is just as hard as 10. Andrea's solution requires extrapolation which is best avoided if interpolation is an option and 11 and 12 are not perfect squares.</span>
