Jawaban:
190 m²
Penjelasan dengan langkah-langkah:
panjang = 4 + 2 + 2 + 3 = 11 cm
lebar = 5 + 4 = 9 cm
panjang teras = 4 cm
lebar teras = 1 cm
skala = 1 : 200 (untuk luas skala ×10² = 1 : 20.000)
..
Luas rumah = 11 × 9 = 99 cm²
Luas Teras = 1 × 4 = 4 cm²
Luas Bangunan = 99 - 4 = 95 cm²
luas sebenarnya = luas denah ÷ skala
= 95 ÷ 1/20.000
= 95 × 20.000/1
= 1.900.000 cm²
= 190 m²
