tolong dijawabkan nomor 26 ya

panjang = 4y = 4 x 6 = 24 cm
lebar = 3y = 3 x 6 = 18 cm
L = p x l
432 = 4y x 3y
432 = 12 y^2
y^2 = 432/12 = 36 cm
y = √36 = 6 cm

Keliling = 2(p+l)
= 2(24+18) = 2 x 42 = 84 cm

P:L =4:3
L PP=4X *3X
432 =12X^2
36=X^2
6=X
p=4X=4*6=24
l=3X=3*6=18

●K=2(p+l)
=2(24+18)
=2(42)
=84
Jawaban [B]

Semoga membantu
