Explanation:

Identify the given values and conversion factor

Given value: \(55\text{ cm}\)
Conversion factor: \(1\text{ inch} = 2.54\text{ cm}\)

Convert centimeters to inches

$$ \text{Size in inches} = \frac{55\text{ cm}}{2.54\text{ cm/in}} $$

Calculate the final value

$$ \text{Size in inches} \approx 21.6535\text{ in} $$

Rounding to two decimal places gives \(21.65\text{ in}\).
