It may seem easy to find the area of a plane figure like a rectangle or a square, but what if the figure has more than four sides or if it is irregular?

In this module, you will understand how to partition an irregular figure into squares and/or rectangles to find the area of the irregular figure.

After going through this module, you are expected to find the area of irregular figures made up of squares and rectangles using sq. cm and sq. m.
