*L = p × l
48 = 6 × l
48/6 = l
8 = l
* Kell = 2( p + l )
= 2 ( 6 + 8)
= 12 + 16
= 28 cm (C)
Jadi Kell persegi pnjang trsbt adlah 28 cm.

Answer 2

Verified answer

Bangun Persegi Panjang.
Panjang = 6 cm
Luas = 48 cm2
Keliling =...?
Jawab :
Rumus =>
L.p.panjang = panjang x lebar
Cara =>
48 = 6 x lebar
lebar = 48/6
lebar = 8 cm
Maka,
Rumus =>
K.p.panjang = 2 (panjang + lebar)
K.p.panjang = 2 ( 6 + 8 )
K.p.panjang = 2 ( 14 )
K.p.panjang = 28 cm ( C )
Jadi,keliling bangun persegi panjang tersebut 28 cm ( C )
