Earth's surface area is 510.07 million km²
There are 100ha in 1km squared.
there are 100 hectares in 1 km squared
Answer: 10000 m² = 0.01 km²
22 m2 is 0.000022 km2
1,000,000m² 1 km squared = 1,000m x 1,000m = 1,000,000m²
Answer: 10,000 m² = 0.01 km²
Europe is 33,398,950,131.23 feet squared. It is 10,180,000 km squared.
661 848 km squared
The answer is ambiguous because of the distinction between a km squared and a square km. The ambiguity arises because n (km squared) is not the same as (n km) squared [except when n = 0 or 1] and it is not always clear which of the two is intended. 86300 km squared could be a square with sides of 86300 km and so an area of 86300*86300 square km. On that basis, 86300 km squared = 7 447 690 000 sq km = 2 875 569 185.16 sq miles. On the other hand 86300 square km = 33320.62 sq miles
1 sq km = 1,000,000,000,000 sq mm
1 km = 1,000 m(1 km)2 = (1,000 m)21 km2 = 1,000,000 m2
202 square km
