Final answer:
To calculate the federally owned land in Maine, multiply 0.8 by Maine's total land area of 19,847,680 acres, which equals about 15,878,144 acres.
Step-by-step explanation:
The question is about calculating the amount of federally owned land in Maine based on a percentage.
Maine has a total of 19,847,680 acres, and about 0.8 (which means 80%) of the land is federally owned.
To find the number of acres federally owned, we need to take 80% of the total land area:
0.8 (80%) of 19,847,680 acres = 0.8 × 19,847,680
Therefore, 0.8 × 19,847,680 = 15,878,144 acres.
15,878,144 acres of land in Maine are federally owned.
