Question

If Earth has 150,100,000km2 of land area, how much land area is included in the biodiversity hot spots?

Answer 1

Answer:

Since earth has 150,100,000km² of land area and hot spots originally covered 15.7% of Earth's surface.

Then,we get the equation

x=0.157.150,100,000

x=23565700

where land area is included in the biodiversity hotspots idenoted with x.

Therefore,23565700km² land area is included in the biodiversity hot spots.
