plis yah jawab plis banget

Ukuran dalam cm
p = 12m = 1200cm
l = 8m = 800cm

Ukuran dalam gambar
p = 1200 : 50 = 24
l = 800 : 50 = 16

Luas dalam gambar
L = p x l = 24 x 16 = 384 (C)

Ukuran Sebenarnya = 12 m × 8 m
Skala = 1 : 50
Panjang pd gambar = 12 × 1/50 = 12/50 = 0,24 m = 24 cm
Lebar pd gambar = 8 × 1/50 = 8/50 = 0,16 m = 16 cm
Luas pd gambar = 24 × 16 = C. 384 cm²
