tolong ya kk no 7 pakai cara

Mapel : Matematika
Bab: Skala

S = 1 : 400
p × l = 5 × 3

Lp = Pp × s
Lp = 5 × 400
Lp = 2.000 cm^2

Ll = Pl × s
Ll = 3 × 400
Ll = 1.200 cm^2

LS = Lp × Ll
LS = 2.000 × 1.200
LS = 2.400.000 cm^2
LS = 240 m^2

L=3x400=1200cm
P=5x400=2000cm
Luas=1200x2000=2.400.000cm²
=2.400.000:10.000=240m²
Maaf kalo salah ya
