The area of the original 13 colonies is now this many states.

The area of the original 13 colonies encompasses a significant portion of what are now the northeastern United States and part of the southeastern region. These original colonies laid the groundwork for the future states that would emerge from their territories.

As the United States expanded beyond the original colonies, the land was divided and reorganized, leading to the creation of additional states over time. The correct answer of 16 reflects the modern configuration of these regions, which includes not only the states that were formed directly from the original colonies but also those that developed from the surrounding territories that were influenced by them.

The count of 16 incorporates states such as New York, Pennsylvania, and Virginia, as well as others that were part of the broader area formerly known as the 13 colonies. This is why the answer highlights the number of states that now exist, showing the historical significance and geographical growth stemming from the original colonies.
