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

OA: C
My answer is D.

the minimum size must be bigger than 5.5

so the minimum area must be bigger than:

size1*zize1=5.5*5.5=30.25

so the area must be bigger than 30.25 and the most close and bigger is 33.75

(D) is the correct answer, as 5.5 * 5.5 = 30.25.

What's the source of the question? Any time you're unsure of a question's validity, providing the source allows us to determine how reliable the question likely is.
