How ‘thread graph’ is used to measure the area ofirregular figures? Discuss withanexample.
Thread graph is a method of finding the area of an irregular figure by using a thread or a string to outline the shape and then measuring the length of the thread using a ruler. The thread is tightly wrapped around the perimeter of the figure, and then the length of the thread is measured using a ruler. The length of the thread is proportional to the perimeter of the shape, which can then be used to calculate the area of the figure.
To measure the area of an irregular figure using a thread graph, the following steps can be followed:
-
Take a piece of thread or string and wrap it tightly around the perimeter of the figure. Be sure to follow the shape of the figure as closely as possible.
-
Once the thread is wrapped completely around the figure, cut the thread at the point where it overlaps with the starting point.
-
Carefully straighten out the thread and measure its length using a ruler.
-
Use the measured length of the thread to
