Paragraph: A wheel of a car is made up of two parts (1)the central metal rim, and (2)the rubber tyre. The width of the tyre $W=16.5 \mathrm{~cm}$ and height $h=10.7 \mathrm{~cm}$. The rim overlaps the tyre. The total weight of the car is 1500 kg distributed evenly. The tyres are inflated with air to a pressure $2.0 \mathrm{~kg} / \mathrm{cm}^2$. The density of air at pressure of $1.0 \mathrm{~kg} / \mathrm{cm}^2$ and at room temperature equals 1.29 g /litre. The outer diameter of the tyre is 55.4 cm and that of the rim is 40 cm . Ignore the thickness of rubber and use the dimensions given here. Note that the units mentioned above are conventional units used in everyday life.
Question: The left side front tyre was observed to be in contact with the road over a length $L \mathrm{~cm}$. The value of $L$ is
