Given a reference text about Adventfjorden, how wide and long is it?

Context: Adventfjorden is a 7 km long and 4 km wide bay running south-eastwards from the southern side of Isfjorden, on the west coast of Spitsbergen in Svalbard. The name represents a corruption of Adventure Bay - probably named after the Hull-built whaleship Adventure, which operated in Isfjorden in 1656. The fjord was originally known as Klass Billen Bay. At the head of Adventfjorden is Adventdalen.

The former mining-camp of Longyearbyen lies on the fjord's southwestern shore, while another former mining-camp, Hiorthhamn, is located on its northeastern shore.

Answer: Adventfjorden is 4km wide and 7km long.
