Let's solve these metric conversion problems:**7. Berapa banyak hektar setara dengan 300 a?*** **Understanding the units:** 'a' stands for ares, and 'ha' stands for hectares. 1 hectare (ha) is equal to 100 ares (a).* **Conversion:** To convert ares to hectares, we divide the number of ares by 100.* **Calculation:** 300 a / 100 a/ha = 3 ha* **Answer:** The correct answer is **A) 3 ha****8. Berapa mm² setara dengan 65 ca?*** **Understanding the units:** 'ca' stands for centiares. 'mm²' stands for square millimeters. 1 centiare (ca) is equal to 1 square meter (m²), and 1 m² is equal to 1,000,000 mm².* **Conversion:** We need to convert centiares to square meters and then to square millimeters.* **Calculation:** * 65 ca = 65 m² (since 1 ca = 1 m²) * 65 m² * 1,000,000 mm²/m² = 65,000,000 mm²* **Answer:** The correct answer is **B) 65.000.000 mm²**
