The rule of significant figures when multiplying numbers is that the number of significant figures of the product must be that of the least number of significant figures of the factors.

The factors are 2.2 which has 2 significant figures and 5.00 which has 3 significant figures. Therefore, the product must only have 2 significant figures.

The answer is B. 11 mm2
