Jawaban:

(1) actual area = 320 km²

(2) map area = 2 cm²

Penjelasan dengan langkah-langkah:

scale = 1 cm to 8 km

scale = 1 : 800.000

(1) map area = 5 cm²

actual area = 5 × (800.000)²

actual area = 5 × 640.000.000.000

actual area = 3.200.000.000.000 cm² ÷ 10.000.000.000

actual area = 320 km²

(1 km² = 10.000.000.000 cm²)

(2) actual area = 128 km² = 1.280.000.000.000 cm²

map area = 1.280.000.000.000 ÷ (800.000)²

map area = 1.280.000.000.000 ÷ 640.000 000.000

map area = 2 cm²
