helep otak saya ngeleg karna saya gk jago MTK helep saya udh telat kirim tugas Jawab: 1. = Luas sisi alas + ( 4 × sisi tegak) = (p×l) + ((2/ × p×t/2/ ) + (2/ × l×t/2/)) = (p×l) + (p×t) + (l×t) = (12 cm × 6 cm) + (12 cm × 10 cm) + (6 cm × 10 cm) = 72 cm² + 120 cm² + 60 cm² = 250 cm² 2. = Luas sisi alas + ( 4 × sisi tegak) = (p×l) + ((2/ × p×t/2/ ) + (2/ × l×t/2/)) = (p×l) + (p×t) + (l×t) = (12 cm × 6 cm) + (12 cm × 8 cm) + (6 cm × 8 cm) = 72 cm² + 96 cm² + 48 cm² = 216 cm² 3. =Luas sisi alas + ( 4 × sisi tegak) = (p×l) + ((2/ × p×t/2/ ) + (2/ × l×t/2/)) = (p×l) + (p×t) + (l×t) = (7 cm × 7 cm) + (7 cm × 15 cm) + (7 cm × 15 cm) = 49 cm² + 105 cm² + 105 cm² = 259 cm² 4. = Luas sisi alas + ( 4 × sisi tegak) = (p×l) + ((2/ × p×t/2/ ) + (2/ × l×t/2/)) = (p×l) + (p×t) + (l×t) = (16 cm × 9 cm) + (16 cm × 13 cm) + (9 cm × 13 cm) = 144 cm² + 208 cm² + 117 cm² = 469 cm² Penjelasan: 2/ itu maskudnya 2 nya di coret ya.. p×t/2...
