Thank you so much!

To determine which is the smallest borough in New York City between Manhattan and the Bronx, we can look at their respective land areas.

Manhattan is located on Manhattan Island and has a land area of about 22.82 square miles (59.13 square kilometers).

The Bronx, on the other hand, is located on the mainland and has a land area of about 42.47 square miles (109.04 square kilometers).

From these measurements, we can see that Manhattan is smaller than the Bronx in terms of land area, making it the smallest borough in New York City.
