Should be D.

The minimum value for each side can be 5.5 cm, so that each is 6 cm when rounded to the nearest cm. Minimum area = (5.5)^2 = 30.25 sq. m

I calculated D too. But OA is given C

5.5 x 5.5 = 30.25 (D)

E. 25.00 sq cm

Though there might be some technicalities concerning the term "nearest" (as 5.5 is equidistant from both 5 and 6) the answer still should be D: 5.5^2=30.25.

If we inspect the OA, option B & C are NOT perfect squares... IGNORE those

Answer has to be above 25 but below 36

Only 30.25 fits in

What is the smallest number that could be rounded to the nearest digit and turn out to be 6 ---> 5.5

Area = 5.5 * 5.5 = 30.25
