Question

While measuring the length of a knitting needle, the reading of the scale at one end is $3.0\mathrm{cm}$ and at the other end is$33.1\mathrm{cm}$. What is the length of the needle?

Answer 1

Explanation:

Given measurement of one end of the needle is $3.0\mathrm{cm}$ and that of the other end is $33.1\mathrm{cm}$. The difference between these readings gives the magnitude of the length of the needle.

$\mathrm{Length}\mathrm{of}\mathrm{the}\mathrm{needle}=33.1-3.0=30.1\mathrm{cm}$

Therefore, the length of the needle is $30.1\mathrm{cm}$.
