Question

Bret’s uncle owns a square of land that is 10 miles long on each side. is that the same as 10 mi2?

Answer 1

No it's not the same.

First of all, miles is used for length while mi2 is used for Area.

Second, if the length of each side is 10 miles , the total area would be 10 x 10 = 100 mi2

hope this helps
