Answer:
Total cost of removing concrete = Rs. 1296
Step-by-step explanation:
Concrete Area = Total Area - Non-Concrete Area
Subtracting width of the path from all the sides we get,
Length = 20 - 4 - 4
= 12 m
Breadth = 15 - 4 - 4
= 7 m
∴ Concrete Area = (20 × 15) - (12 × 7)
= 300 - 84
= 216 square meters
Total cost of removing concrete = Rate × Area
= 6 × 216
= Rs. 1296
