C’mon everyone... this land is your land/ this land is my land… no? Ok. Party poopers.
It’s just a vanilla area conversion problem. They give us that 100 kilometers is 62 and
a half miles so if we take that to the unit level, 1 kilometer is about .625 miles.
Since 1 kilometer is about .625 miles, this tells us that miles are bigger than kilometers.
Makes sense. America’s bigger than England.
They give us the 64 kilometers as part of the question.
So we can immediately eliminate C and D, since only 2 of the answers are less than 64.
To convert kilometers and miles to SQUARE kilometers and SQUARE miles, we can just square .625.
Since we want to find the how many square miles are in 64 square kilometers, we can
multiply .625 times 64 to get 25 miles squared.
Looks like the answer is A.
