Penjelasan dengan langkah-langkah:
panjang 9 cm
p : l = 3 : 2
lebar
l = 9/3 . 2
l = 6 cm
Luas persegi panjang
L = p . l
L = 9 cm . 6 cm
L = 54 cm^2
Jawaban:
panjang = 9cm
panjang : lebar = 3 : 2
luas persegi = ?
lebar ?
3/2 = 9/x
3x = 18
x = 18/3
x = 6cm
luas ?
luas = p x l
luas = 9cm x 6cm
luas = 54cm²
