Question

write an activity to measure the length of curved line using a scale and thread​

Answer 1

We have to take a scale and thread first of all.

We then take the thread and trace it exactly on the curved line. Once we have received this thread measurement, we will place it on a flat surface and measure it with a scale/ruler. The length we get is the length of the curved line.

Answer 2

Explanation:

Measuring Length of a Curved line

Tie a knot at one end of the thread.

Place the thread at the beginning of the line and try to measure a small initial portion of the line which is relatively straight.

Place your thumb at the other end of the measured portion and measure next straighter portion.

Repeat the above step till the end of line is reached.
