1. hasil dari 8! + 8! adalah 80.640
2. banyak lampu yg dapat dipasang adalah 120
= 8! + 8!
= ( 8 × 7 × 6 × 5 × 4 × 3 × 2 ) + 8!
= 40.320 + 8!
= 40.320 + ( 8 × 7 × 6 × 5 × 4 × 3 × 2 )
= 40.320 + 40.320
= 80.640
mencari keliling
k = 2 × ( p + l )
k = 2 × ( 30 + ( 2 × 30 ) )
k = 2 × ( 30 + 60 )
k = 2 × 90
k = 180 m
konversi ke satuan cm
= 180 × 100
= 18.000 cm
mencari banyaknya lampu
= 18.000 ÷ 15
= 120
