Gambar: persegi panjang, panjangnya 6 cm, lebarnya 3 cm. Gambar di samping memiliki skala 1: 500. Berapakah luas sebenarnya? (p.s plisss jawab hari ini besok di periksa and pake rumus)

Skala 1 : 500 = 1 cm di gambar = 500 cm di lapangan = 5 meter
panjang asli = 6 cm -> 6 cm x 5 = 30 meter lebar asli = 3 cm -> 3 cm x 5 = 15 meter
Luas = p x l = 30 x 15 = 450 meter persegi

Skala 1 : 500 = 1 cm di gambar = 500 cm = 5 meter
panjang asli = 6 cm -> 6 cm x 5 = 30 meter lebar asli = 3 cm -> 3 cm x 5 = 15 meter
panjang asli = 6 cm -> 6 cm x 5 = 30 meter
lebar asli = 3 cm -> 3 cm x 5 = 15 meter
Luas = p x l = 30 x 15 = 450 meter persegi
panjang asli = 6 cm -> 6 cm x 5 = 30 meter
lebar asli = 3 cm -> 3 cm x 5 = 15 meter
L = p × l
= 6 cm × 3 cm
= 18 cm2
