a-50% of america’s urban areas, or more than 10 million acres.
b-50% of america’s west coast, or 35 million acres.
c-20% of america’s east coast, or more than 5 million acres.
d-10% of all american land, or more than 270 million acres.

d-10% of all American land, or more than 270 million acres.

Explanation:

The settlers were a society that had agriculture as the main source of family income. However, for promising agriculture, good climatic and soil conditions are needed, as well as quality agricultural tools. But what the settlers encountered were challenges of the severe prairie climate and precarious agricultural conditions, and for that reason, they settled in 10 percent of the entire American land, or more than 270 million acres.
