Measuring curved line
 
Method:
  • Draw a curved line \(AB\) on a piece of paper
  • Place a string along the curved line. Make sure that the string covers every bit of the curved line.
  • Mark the points where the curved line begins and ends on the string.
  • Now, stretch the string along the length of a meter scale and measure the distance between the two markings of the string. Note it.
  • This will give you the length of a curved line.
