Question

Explain how one can measure length of a curved line using a string or thread.​

Answer 1

Answer:

The length of a curved line AB can be measured by using a thread and a ruler.

Firstly, tie a knot at the one end of the thread. Place the knot at point A. Take the thread along a small part of the curved line. Keeping that part pressed with our fingers, carefully straighten the thread along another small part of the line. Keep moving along the line till we reach the point. Make a marking on the thread where it coincides with point B. Using a ruler, measure the length of the thread from the initial knot to the final marking. This gives the length of the curved line AB.
