Area of rectangle - L × B
- 140 cm × 12000cm
- 16,80,000cm²
- 16,800m²
Cost of polishing 1m² - Rs. 52
Cost of polishing 16,800m² - 16,800 × 52

Answer:
The cost of polishing the floor will be ₹ 8736
Step-by-step explanation:
Here the length and the breadth of a floor is given
length = 140 cm
= 140/100
= 1.4 m
breadth = 120 m
We will first find out the area of the floor
area of floor = length × breadth
= 1.4 × 120
= 168 m²
Now, the rate of polishing is given to be ₹ 52 per square metre
cost of polishing floor = area of floor × rate
= 168 × 52
= 8736
