soal:
p : 8
l : 4
t : 7
ditanya:
luas permukaan??..
Liahatlah tangannya hampir patah karena memencet like trllu bnyk._.
Diket:
p = 8 cm
l = 4 cm
t = 7 cm
Ditanya: Lp?
Jawab:
Lp = 2 × ((p × l) + (p × t) + (l × t))
= 2 × ((8 × 4) + (8 × 7) + (4 × 7))
= 2 × (32 + 56 + 28)
= 2 × 116
= 232 cm²
- lp = 2 × ( pl + pt + lt )
- lp = 2 × ( 8 . 4 + 8 . 7 + 4 . 7 )
- lp = 2 × ( 32 + 56 + 28 )
- lp = 2 × 116
- lp = 232 satuan luas persegi panjang
