Panjang sebenarnya = 7 : 1/200 = 7 × 200/1 = 1.400 cm = 14 m Lebar sebenarnya = 4,5 : 1/200 = 4,5 × 200/1 = 900 cm = 9 cm Luas sebenarnya = p × l = 14 m × 9 m = 126 m (C)

7 cm x 4,5 cm7.200 cm x 4,5.200
1400 cm x 900 cm
14 m x 9 m
126 m²
= 7 : 1/200 = 7 × 200/1 = 1.400 cm = 14 m
Lebar sebenarnya
= 4,5 : 1/200 = 4,5 × 200/1 = 900 cm = 9 cm
Luas sebenarnya
= p × l = 14 m × 9 m = 126 m (C)
