81 - 15 = 66

49 - 15 = 34

One year ago 33 = half 66

There is no 'formula'. The square numbers requirement gives a limited number of possibilities, and the fact that Belinda's age now is divisible by 2 eliminates about half of those. It's then just a matter of working through the remaining possibilities.
