Answer:
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.
Step-by-step explanation:
A boy carved his initials on the bark of a tree at a height of 2.5m above the ground when the tree was 5m tall. In 10 years the tree attained a height of 15m. The initials carved by the boy 10 years ago will now be found.
