Answer

55.12 in (to nearest 2 decimal places)

Work Step by Step

First, convert dm to cm: 1dm = 10cm 14dm = 140cm Second, convert cm to inches by dividing by the value 2.54: 1 in = 2.54 cm $\frac{1}{2.54} in = 1 cm$ $\frac{140}{2.54} in = 140cm$ Ans = $\frac{140}{2.54}$ in = 55.1181102362 in $\approx 55.12$ in (to nearest 2 decimal places)
