Estimating implies that the number is approximate to the desired value so any number squared that is close to the desired estimation would be considered close enough. Rounding off is a form of estimating and has a set of rules that accompany it. For simple estimating, (non-medical, hazardous items not included) like "what is the square root of 169". it would be about 13X13 or 13 squared. Get closer by finding the factors of 169. and simplify.
