Q10

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

这题我觉得最大的误差应该是5.5,这样算出来的面积是 D.30.25 sq cm

而答案给出的是C,是怎么算出来的?
