Verified answer
Materi : Bangun Datar
Panjang Persegi Panjang (270 cm²)
p² = L(persegi panjang [144 cm²]/p¹ + 12
p² = 144 cm²/15 cm + 12 cm
p² = 12.4/5 cm + 12 cm
p² = 9,6 cm + 12 cm
p² = 21,6 cm
Langsung Saja ( x = lebar )
panjang × lebar = luas
21,6 cm × lebar = 270 cm²
lebar = 270/21,6 cm
lebar = 12,5 cm
Semoga bisa membantu

x = 144/15 + 12
= 144/32
= 9/2
= 4,5 CM
MAKA :
4,5L = 270
L = 270/4,5
L = 60/1
L = 60 CM
