Verified answer
Keliling = 48 m = 4.800 cmskala = 1:200
panjang sisi sebenarnya
keliling = 4 x s
4.800 = 4 x s
s = 4.800 / 4
s = 1.200 cm
panjang sisi pada denah
= panjang sisi sebenarnya : skala
= 1.200 : 200
= 6 cm
= 48 : 4 = 12 m = 1200 cm
panjang gambar denah
= skala x panjang sisi rumah asli
= 1:200 x 1200
= 1200/200
= 6 cm
