Penjelasan dengan langkah-langkah:
19 ) Dik = p = 10,cm
L = 5 cm
t = 4cm
Dit = LPB ............?
LPB = 2 (PL + PT + LT)
= 2 ( (10.5) + (10.4) + (5.4) )
= 2 ( 50 + 40 + 20 )
= 2 . 110
= 220 cm2
jadi,LPB adalah A. 220 cm2
20 ) Dik = Pk1 = 54 cm
Dit = lpk. ......?
LPK = 6 × ( L . L )
= 6 × ( 54 × 54 )
= 6 × 2.916
= 17.496 cm2
jadi, LPK adalah 17.496 cm2
maaf klo salah
