Whilemeasuring the length of a knitting needle, the reading of the scaleat one end is 3 cm and at the other end is 33.1 cm. What is thelength of the needle?
Thereading of the scale at one end is 3 cm and at the other end is 33. 1cm.
Therefore,the length of the knitting needle is given by subtracting both thereadings, i.e., (33.1− 3.0) cm = 30.1 cm.
