Answer:
In 1630 at the beginning of European settlement, about 425,000,000 hectares of the US were forested. By 2017, the area of forested land has declined to 300,000,000 hectares. What is the percent decrease of forested land between 1630 and 2017?
1630= 425000000
2017= 300000000
decrease= 125,000,000
percentage decrease= 125000000/425000000 x 100
percentage decrease= 29.41%
