panjang model pesawat = a = 32cm
lebar model pesawat = b = 24cm
panjang sebenarnya = p = 28m
lebar sebenarnya = l = x ??
a/b = p/l
32cm/24cm = 28m/x
32cm/24cm = 2800cm/x
4/3 = 2800cm/x
x = 2800 × 3/4
x = 2100cm ➡ 21m
semoga membantu
Lebar pd peta = 24 cm
Pnjng sebenarnya = 28 m = 2800 cm
Lebar sebenarnya
= 2800 cm : 32 cm = 87,5
= 24 × 87,5
= 2100 cm = 21 m
