Think of mm2 as (mm)2=(mm)×(mm). the squared mm are actually two millimeter units, each of which must be converted separately. to convert 130mm2 to square meters, you would use the following calculation: 130mm2×(1m1000mm)×(1m1000mm)=130mm2 ×(1m1000mm)2suppose that, from measurements in a microscope, you determine that a certain layer of graphene covers an area of 2.30 μm2. convert this to square meters. express the area in square meters to three significant figures.
