Explanation:

Step1: Add the values

$22.033 + 34.045+5.5040=61.582$

Step2: Apply significant - figure rules for addition

When adding, the result should be rounded to the same number of decimal places as the number with the least number of decimal places among the values being added. Here, all values have three decimal - places initially, but we report to one decimal place as per significant - figure rules for addition. Rounding $61.582$ to one decimal place gives $61.6$.

Answer:

A. $61.6$ cm
