Greenland is the largest island in the world. What is its area? Territory belonging to that country?

2.1756 million square kilometers, Greenland (Greenland, Kalaallit Nunaat) (Denmark) is the world's largest island. Located in northeastern North America. About 4/5 of the island is within the Arctic Circle. The coastline is 44,000 kilometers long. The annual average temperature is below 0 ℃, and the lowest can reach -70 ℃. The big brother of the global islands. The front lines of a warming planet. No one knows exactly when Greenland's indigenous people came here and why they chose such a desolate place to live. When the Icelandic colonists arrived here in 982, they found it uninhabited. At the extreme south end of the island, the Icelanders established three strongholds that they held on to for the next few centuries. Greenland is the hometown of Santa Claus. The name Greenland was given by these Scandinavians. According to the Norse mythology epic saga, Erikson the Red Beard fled from Iceland to this place after committing murder. The Erikson family and their slaves sailed northwest to discover a land rumored to exist there. When he settled on the island, he named the island Greenland (meaning "green land") to attract more immigrants. (At least the fjord at the southern end of the island was still grassy.) His clever plan worked, and the Nordic settlers were able to live in harmony with the newly arrived Inuit people. In the 12th century, a Catholic bishopric was even established in Greenland. In 1386, Greenland officially belonged to Norway. Since Norway was a member of the Kalmar Union of the three Nordic countries at that time, after the union collapsed, Greenland fell under the rule of the Danish-Norwegian dual monarchy. After persisting for more than five hundred years, the Norse settlements suddenly disappeared in the 15th century, most likely due to widespread food shortages caused by the Little Ice Age. The remains of residents of this period that were later discovered showed signs of malnutrition.
