Question

Give reasons for the following questions.

1. Metre cannot be used to measure all the lengths but it's multiples and Submultiples are required for correct measurement.

Plzz answer guys

Answer 1

metre is used to measure small quantities but it's multiple and submultiples are required for correct measure because if it is long like distance between earth and moon we can't measure but with it multiple we can measure to example A

Answer 2

because if the distance is smaller than one metre it cannot be used in that case cenimetere will be used which is sub multiple of meters and if say for example the distance is 1000metere 1kilometre can be used for more accurate answer
