how can we measure a length of a curved line

 

Procedure to Measure the Length of a Curved Line

  • Take a non-stretchable string or a thread and tie a knot at one of its ends.
  • Place the knotted end of the thread at one end of the curved line.
  • Holding the thread steadily with your fingers, and stretch it along the curved line until you reach the other end.
  • Now make a mark on the thread where it reaches the other end.
  • Finally, place the thread along a metre scale and measure the length between the knot and the marked point.
  • This gives the length of the curved line.
