If Georgia is 59,424.77 square miles, then what is the area of Georgia rounded to the nearest square mile?

Answers

59,424.77 rounded to the nearest square mile would be 59,425 because the .77 would get rounded up to a 1. That 1 gets added to the 424, hence 59,425.

59,424.77's tenths is 7 which means we had to rounded up instead of keeping the ones, so if we add the 1 that had represented the 7 on the tenths, then 59,424+1=59,425, which means the answer would be 59,425.
