The length of a curved surface is measured by using both the metre scale and the thread.
Explanation:
the measuring of length of a curved surface, first take the measure of length using a thread and then find out the numerical value of that length of thread using scale. This numerical value will give the length of the curved surface. Thus, both thread and scale are used to find out the length of a curved surface.

Answer:
with thread trace the curved line
then cut it to its length
then measure the length of thread using g a scale and there you go
