Answer 2

Given,

The total number of lengths$\[ = 10\]$

The average of the given lengths$\[ = 8.3{\rm{cm}}\]$

Solution,

Know that by multiplying the average of a quantity with the total number of quantity one shall get the sum of the quantities.

Therefore, the total length is given as

$\[\begin{array}{l} = 10 \times 8.3{\rm{cm}}\\ = 83{\rm{cm}}\end{array}\]$

Hence, the correct option is (c) i.e.$\[83{\rm{cm}}\].$
