Class 9 Solved Practice Questions
1
Convert 2 Aana 3 Paisa into Square Meters (m²) & Square Feet (ft²).
• 1 Aana = 31.796 m² (342.25 ft²) ➔ 2 Aana = 2 × 31.796 = 63.592 m²
• 1 Paisa = 7.949 m² (85.56 ft²) ➔ 3 Paisa = 3 × 7.949 = 23.847 m²
Total Area = 63.592 + 23.847 = 87.439 m² (approx 941.18 ft²)
2
Convert 5 Kattha 10 Dhur into Square Meters (m²) & Square Feet (ft²).
• 1 Kattha = 338.63 m² (3,645 ft²) ➔ 5 Kattha = 5 × 338.63 = 1693.15 m²
• 1 Dhur = 16.93 m² (182.25 ft²) ➔ 10 Dhur = 10 × 16.93 = 169.30 m²
Total Area = 1693.15 + 169.30 = 1862.45 m² (20,047.5 ft²)
