The Great Zimbabwe was the center of a huge trading empire.
a thriving city by the time Europeans arrived in the subregion.
where the remains of the earliest humans were found.
the home of Shaka and his powerful army.

the answer would be the third option, "no, ariel should have added 9^2 and 12^2 and compared that to 15^2."

this is found through the pythagorean theorem, which is a^2 + b^2 = c^2.

this is the correct way of solving the problem:

9^2 + 12^2 = 15^2

81 + 144 = 225

225 = 225
