kebun pak nyoman mempunyai keliling 198 m. perbandingan panjang dan lebarnya = 6 : 5. luas kebun pak nyoman adalah...cm

misal
panjang = 6x
lebar = 5x

K = 2 × (p + l)
198 = 2 × (6x + 5x)
198 = 2 × 11x
198 = 22x
x = 198 ÷ 22
x = 9

jadi
panjang = 6x = 6 × 9 = 54 m
lebar = 5 × 9 = 45 m

Luas
L = p × l
= 54 × 45
= 2430 m²
= 24.300.000 cm²

198 = 2(6x + 5x)
x = 198/22= 9 meter
panjang = 6x = 54 meter
lebar = 5x = 45 meter
luas = 2430m² = 24300000 cm²
