1.	By using thin cotton tthread how will you find the length of a curved line
Answer» Since the scale is a straight and it is very hard to bend it for getting the correct measurement of the curve line. Thus we need MUCH more flexible MEASURING thing to measure the curve line. So, a non-stretchable string or a THREAD is used to measure the length of curved line. Hence, both the ASSERTION and reason STATEMENT are correct and reason explains the assertion very well. HOPE IT WILL HELP YOU
