This question asks us to determine whether a measurement is a measurement of length, area, volume, mass, density, time, or temperature. The measurement is 1.06 micrometers. (Note, the unit is actually given as the greek letter mu followed by an additional m for meters. However, the letter mu can not be displayed in this interface.) Mu indicated that the quantity is micro, which is equal to 10e-6 of the base unit. Micrometers are a unit of length, indicated by the presence of "meter" in it. There is no real math here, just memorizing units.
