Answer: 5.4 million km2
Explanation:
In 1994, the amazon rainforest covered 6.42 million square kilometers. In 2014, it covered 50/59 as much. This means that in 2014, the amazon forest covered 50/59 of 6.42 million square kilometers. Mathematically, this is:
= 50/59 × 6.42
= 5.4407 square kilometers
= 5.4 million square kilometers
