Question

while measuring the length of a knitting needle,the reading of the scale at one end is 3.0cm and at the other end is 33.1cm.what is the length of the needle?​

Answer 1

Given,

• Reading of the scale at first end = 3 cm

• Reading of the scale at last end = 33.1 cm

Here,

The length of the knitting needle is the difference between two ends.

$\sf{\implies Length \ of \ needle=33.1-3}$

$\sf{\implies Length \ of \ needle=30.1 \ cm}$

$\boxed{\sf{\therefore Length \ of \ needle=30.1 \ cm}}$
