To determine which length is longer, we can compare the two lengths by looking at the hundredths place. In this case, 21.5 inches is longer than 21.05 inches because 21.5 has a higher value in the tenths place than 21.05. The tenths place is the second digit after the decimal point, so 21.5 is longer than 21.05 by 0.45 inches.
