jawab pertanyaan diatas yaaa pake cara

p = 4,2 cm
l = 1,8 cm

K = 2(p + l) = 2 × (4,2 + 1,8) = 2 × 6 = 12 cm

Denah peta 1 : 500, berarti
1 cm denah = 500 cm asli
12 cm denah = x cm asli

Gunakan rumus perbandingan silang (kali silang)
x = 500 × 12 ÷ 1 = 6000 cm = 60 m


Biaya yg dibutuhkan
= 125000 × 60
= 7500000
