One hundred sixty acres is a square with a
side length of one-half a mile. How many
hectares are in one square mile?

But how did they get that answer? I want to know how to do it.
You just learn or look up that 1 square mile equals about 259 hectares.
To find out how many hectares are in one square mile, we need to convert the units from acres to hectares.
First, we need to know the conversion factor between acres and hectares. 1 acre is equal to 0.4047 hectares.
Now, let's calculate the area of one square mile in acres. We know that one side of the square has a length of half a mile, so the area of the square mile is (1 mile) * (1 mile) = 1 square mile.
Since one side of the square represents half a mile, the area of the square mile in acres is (0.5 mile) * (0.5 mile) = 0.25 square miles.
To convert this area to hectares, we multiply by the conversion factor:
0.25 square miles * 640 acres/square mile * 0.4047 hectares/acre = 64.94 hectares
Therefore, one square mile is approximately equal to 64.94 hectares.
