Expert Answer:

25 cm = 0.25 m
Length of the table top = 4m - (2 × 0.25)m = 4m - 0.50m = 3. 5 m
 
Bredth of the table top = 2m - (2 × 0.25)m = 2m - 0.50m = 1. 5 m
 
Area of the table top = l × b = 3. 5 × 1. 5 = 5.25 m2
 
Cost of polishing the table top at ₹25 per square metre = 5. 25 × 25 = Rs. 131.25
