Question:
Volume of water required to spray herbicide in 2 ha land, if 2 litre water is used for a swath of 1.4 m width and 50 m length:
Volume of water required to spray herbicide in 2 ha land, if 2 litre water is used for a swath of 1.4 m width and 50 m length:
Show Hint
Water volume = (Water used for swath Swath area) \(\times\) Total area.
1 ha = 10,000 m\(^2\).
Always convert units consistently.
1 ha = 10,000 m\(^2\).
Always convert units consistently.

The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
We need to calculate the total water volume for spraying.
We have the water used for a swath of specific dimensions.
Step 2: Key Formula or Approach:
Area of swath = Width \(\times\) Length.
Water volume per unit area = Water used Area of swath.
Total water = Water volume per unit area \(\times\) Total area.
Step 3: Detailed Explanation:
Swath area = 1.4 m \(\times\) 50 m = 70 m\(^2\).
Water used for swath = 2 litres.
Water volume per m\(^2\) = 2 70 = 0.02857 litres/m\(^2\).
Total area = 2 ha = 2 \(\times\) 10,000 = 20,000 m\(^2\).
Total water = 0.02857 \(\times\) 20,000 = 571.4 litres.
Step 4: Final Answer:
The volume of water required is 571.4 litres.
Hence, the correct option is (B).
