Question

Persegi pjg
p = 2xl
kell = 48 cm
hitung panjang dan lebar tersebut

Answer 1

Diketahui p = 2 * l
jadi , p + l = 2l + l = 3l
Keliling = 2(p+l)
keliing = 2(3l)
keliling = 6*lebar
48 = 6*lebar
lebar = 8
panjang = 2*lebar = 16 cm

:)

Answer 2

Panjang= 2xlebar
keliling= 2x(p+l)
48=2x(2l+l)
48=6l
8=l

p=2l
p=2x8
=16
