Verified answer
P = 8cm × 2000 = 16000cm = 160ml = 5cm × 2000 = 10000cm = 100m
L = p × l = 160 × 100 = 16000 = 16km^2
ld = 5 cm
skala = 1 : 2.000
Ls = .....???
Ls = (pd × ld) : (skala)^2
Ls = (8 cm × 5 cm) : (1/2.000)^2
Ls = 40 cm^2 : (1/4.000.000)
Ls = 40 cm^2 × 4.000.000
Ls = 160.000.000 cm^2
Ls = 16.000 m^2
Jadi luas sebenarnya rumah tersebut adalah 16.000 m^2
