Step 1: Calculate the area of the square hall.
The area A of a square with side length s is
A=s2.
Given s=8 m,
A=82=64 m2.
Step 2: Calculate the total cost of carpeting.
The cost of carpeting is ₹150 per m2.
Total cost C is
C=A×150.
Substitute A=64 m2,
C=64×150.
64×100=6400,
64×50=3200,
C=6400+3200=9600 ₹.
Final answer: ₹9600
