Answer :

Final answer:

The Aztecs built chinampas, artificial islands, primarily for farmland to support their populous urban center.


Explanation:

Chinampas were artificial islands built by the Aztecs primarily to use as farmland. These rectangular plots were constructed in shallow parts of the lake and secured with anchoring poles to grow crops such as maize, beans, and squash. The surplus produced on chinampas helped sustain the urban Aztec population of Tenochtitlán by providing a reliable food source.
