Chapter 9 - Measurement - 9.2 Measuring Area and Volume - Exercise Set 9.2: 60

Answer

The best unit of measure to express the area of a dollar bill would be square centimeters.

Work Step by Step

The best unit of measure to express the area of a dollar bill would be square centimeters. A dollar bill is several centimeters long and a few centimeters wide, so square centimeters would be the best choice to express the area of a dollar bill.
