Some lengths are given in Column I of Table 5.5. Some units are given in Column II. Match the lengths with the units suitable for measuring those lengths. Table 5.5: Column I - Distance between Delhi and Lucknow, Thickness of a coin, Length of an eraser, Length of school ground; Column II - centimetre, kilometre, metre, millimetre
Distance between Delhi and Lucknow → kilometre; Thickness of a coin → millimetre; Length of an eraser → centimetre; Length of school ground → metre
Explanation
The chapter explains that for measuring larger lengths like distances between cities, we use kilometre (km). For smaller lengths like the thickness of a coin, millimetre (mm) is appropriate. For objects like an eraser, centimetre (cm) is suitable. For medium-sized measurements like a school ground, metre (m) is the appropriate unit.
