Final answer:
The southeast region of the US is roughly within 32°N to 49°N latitude and 80°W to 89°W longitude, with the exact boundaries depending on the specific states considered part of this region.
Step-by-step explanation:
The southeast region of the United States encompasses a range of latitude and longitude coordinates. Specifically, it falls within the broader area of Eastern North America, which extends from Labrador to South Carolina. This means that the latitude range for the southeast region would start from approximately 32°N (North of the equator) and could extend up to around 49°N. However, the core southeastern region would have a lower latitude range, more likely resembling the latitudes of Florida and nearby states. The longitude range for this region, being west of the Prime Meridian, spans from the Eastern Coastline of the United States westward, which could be roughly from 80°W to 89°W, aligning with the eastern seaboard and the central states' eastern borders.
