Trying to figure out which method GMAT opts for when finding the 'round' of a floating number.

Here are the two definitions i got online:

Bankers method: Round(5.5) = 5
Mathematical method: Round(5.5) = 6

Which method does GMAT use?? Is it written anywhere on OG Math??

Knowing 'round' is helpful in solving the following problem!!

The sides of a square region, measured to the nearest centimeter, are 6 centimeters long. The least possible value of the actual area of the square region is

A.36.00 sq cm

B.35.00 sq cm

C.33.75 sq cm

D.30.25 sq cm

E.25.00 sq cm[/i]
