Answer
$\approx 4724.41$ in (to nearest 2 decimal places)
Work Step by Step
First, convert dam to cm:
1dam = 1000cm
1.2dam = 12000cm
Second, convert cm to inches by dividing by the value 2.54:
1 in = 2.54 cm
$\frac{1}{2.54}$ in = 1 cm
$\frac{12000}{2.54} in = 12000cm$
Ans = $\frac{12000}{2.54}$ in = 4,724.4094488189 in
$\approx 4724.41$ in (to nearest 2 decimal places)
