{"text": "### Human: Hitunglah luas segitiga dengan sisi 5 cm, 10 cm, dan 8 cm.. ### Assistant: Untuk menghitung luas segitiga yang hanya diberi panjang sisi-sisinya (a, b, dan c), kita dapat menggunakan rumus Heron. Pertama, kita perlu menghitung setengah perimeter segitiga, yang diberikan oleh: ``` s = (a + b + c) / 2 `` Where a, b, dan c adalah sisi-sisi segitiga. Mengganti nilai-nilai sisi segitiga ke dalam persamaan ini, kita mendapatkan: `` s = (5 + 10 + 8) / 2 s = 11,5 ``` kita dapat menggunakan rumus Heron untuk mencari luas segitiga, yang diberikan sebagai: `` A = sq ((s * s-a) * s-b) * s-c)) ` A adalah luas segitiga, yaitu 1,5 cm persegi, A adalah 1,5 cm persegi, dan b adalah 19,5 cm persegi. * * Sekarang kita mendapatkan persamaan ini: a = c = a = a = a = a = a = a = a = a = a = a = a = a = b = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a = a"}
