Write down the steps involved in measuring the length of a curved line?
Following are the steps involved in measuring the length of the curved line:
1) First of all we have to take a thread.
2) Now place the thread along the path of the curved surface.
3) Mark the thread at the end point up to which you want to measure the length.
4) Place the thread on the scale starting from zero to the marked end point.
5) Measure this length by the help of the scale.
