Detailed Solution

We can measure the length of a curved line with a ruler and string.
A ruler is a tool or device used to measure the length and draw straight lines. A ruler measures the length in both metric and customary units. The rulers are marked with standard distance in centimetres at the top and inches at the bottom, and the intervals of the ruler are called hash marks. The ruler and string can be used to measure the length of the curved line, the string is placed to trace the curved line, and then the length of the string is measured using the ruler.
