@All.
It is based on the assumption that only the steel takes the tension and concrete takes compression.
So in the tension zone i.e, below Neutral Axis Concrete does not take tension therefore it cracks. That's why this section is called as Cracked Section.
In the cracked section (in singly reinforced beams) the total area of the section in terms of the concrete is Area of Concrete in Compression + Area of steel in terms of Concrete.

Transformed area section is right. Transformed area if concrete is equals to modular ratio times area of steel.
