Answer:
Length of knitting needle= 30.1 cm
Explanation:
The reading of scale starts with 0 cm and here, the reading starts from 3 cm.
So, to find the length of of knitting needle, we'll have to subtract the initial unit with such a number that it becomes 0 and the same number should be used to subtract from the other measurement.
The differences of these new measurements will be the length of the knitting needle.
- 3-3= 0cm
- 33.1-3= 30.1cm
Difference = 30.1-0
ㅤㅤㅤㅤㅤ= 30.1 cm
Length of knitting needle = 30.1cm
