How can you measure the area of an irregular object?
The area of an irregular object can be obtained by drawing an outline of the shape of the object on a graph paper of 1 square centimeter marked square. The number of complete squares is counted. Next squares more than half are also counted as a complete square. Squares less than half are left and not counted.
How do we measure the area of irregular objects?
