EXPLAIN HOW ONE CAN MEASURE LENGTH OF A CURVED LINE USING A STRING
Answers
Answer:
measure only just lenght of a string, 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.
To measure a curved line using a string, we have to follow the given steps:
1. Put a knot on the string near one of it's ends.
2. Place this knot on the first point.
3. Now, place a small portion of the string along the line, keeping it taut using your fingers and thumb.
4. Hold the string at this end point with one hand.
5. Using the other hand, stretch a little more portion of the string along the curved line.
6. Keep on repeating this process till the other end of the curved line is reached.
7. Mark a mark on the string where it touches the end. Now stretch the string along a metre scale. Measure the length between the knot in the beginning and the final mark on the thread.
