std 7 ​

Answer 1

Explanation:

The coast, also known as the coastline or seashore, is defined as the area where land meets the sea or ocean,[1] or as a line that forms the boundary between the land and the ocean or a lake.[2] Around 620,000 kilometres (390,000 mi) of coastline are on Earth. Because of the coastline paradox, a coastline's exact perimeter cannot be determined.
