pak yusuf memiliki kebun 450m2,kolam ikan 12 are,dan sawah 0,75 ha.luas seluruh lahan pak yusuf...m2

are = dam2
12 are = 12 dam2
= 1.200 m2
ha = hm2
0,75 ha = 0,75 hm2
= 7.500 m2

luas seluruh lahan
450 m2 + 1.200 m2 + 7.500 m2
= 9.150 m2

450m² + 12 are (12 dam² = 1200 m²) + 0,75 ha (75 dam² = 7500 m²) = 9150 m²
