A TWO-HECTARE RICE FIELD (LENGTH IS TWICE THE WIDTH) IS TO BE HARVESTED BY A STRIPPER COMBINE WITH AN AVERAGE SPEED OF 5 KPH. FIELD SAMPLING SHOWS 0.60 KG PADDY PER SQ. METER. THE COMBINE FINISHES THE AREA IN TWO HOURS.

1. Based on the field area sampling, what will be the total yield of the 2-hectare field (in ounces)?

Step 1: Calculate yield in kilograms.
Area: 20,000 m²
Yield: 20,000 m² × 0.60 kg/m² = 12,000 kg

Step 2: Convert kilograms to ounces.
(1 kg ≈ 35.274 oz)
12,000 kg × 35.274 oz/kg = 423,288 oz

Result: 423,288 oz

2. How wide is the swath of the combine?

Formula: Swath Width = Area / (Speed × Time)

Data:
Area = 20,000 m²
Speed = 5,000 m/h (5 kph)
Time = 2 hours

Calculation:
Swath = 20,000 / (5,000 × 2)
Swath = 20,000 / 10,000

Result: 2.0 meters
