A field is 0.4 km long and 250 m wide. What is its area in hectares? (1 hectare = 10,000 m²)
Answer and explanation
Correct answer: B. 10 hectares
- Step 1: 0.4 km = 400 m. Step 2. Area = 400 × 250 = 100,000 m². Step 3. 100,000 ÷ 10,000 = 10 hectares. Answer: 10 hectares. Why not the others: 100 hectares: This divides 100,000 m² by 1,000 instead of 10,000. 1 hectare: This divides 100,000 m² by 100,000. 100,000 hectares: This leaves the area in square metres and calls it hectares.
