Answer 1

29.41%

Step-by-step explanation:

Given that,

In 1630 at the beginning of European settlement, about 425,000,000 hectares of the United States were covered with trees.

By 2017, the area covered by trees was reduced to 300,000,000 hectares.

We need to find the percentage decrease in the area covered by trees between 1630 and 2017.

The percentage decrease in any value is given by :

`\%=(300,000,000 -425,000,000 )/(425,000,000 )* 100\\\\=29.41\%`

So, the percentage decrease in the area covered by the trees is 29.41%.
