Express the product of 2.2 mm and 5.00 mm using the correct number of significant digits. . a.10 mm2. b.11 mm2. c.11.0 mm2. d.11.00 mm2

We are given with two dimensions: 2.2 mm and 5.00 mm. In this case, we make sure first if the dimensions' units are consistent. Since both are expressed in mm, we multiply readily the two resulting to 2.2*5 or 11.0 mm^2. The answer in this problem is C. 11.0 mm2.
