Solution: The area of the city is $2025$ km², and we are to find how many integer side lengths $s$ correspond to square grid sizes such that $s^2$ divides $2025$. This requires finding the number of positive divisors of $2025$, since each such divisor $s^2$ implies $s$ is an integer divisor of $\sqrt{2025} = 45$.
