Keliling ABC dari gambar di samping adalah.

Materi : Bangun Datar

AC² = AB² + BC²

AC² = 8² + 6²

AC² = 64 + 36

AC² = 100

AC = √100

( AC = 10 cm )

K = AB + BC + AC

K = 8 cm + 6 cm + 10 cm

K = 14 cm + 10 cm

{ K = 24 cm }

Semoga bisa membantu

Jawab:

Penjelasan dengan langkah-langkah:

diketahui

sisi AB = 8 cm

sisi BC = 6 cm

ditanya = keliling ABC?

Mencari sisi AC

$ac^{2} = ab^{2} + bc^{2} \\ac^{2} = 8^{2} +6^{2}\\ac^2} = 64 + 36\\ac^2 = 100\\ac = 10$

Keliling segitiga ABC

K = s + s + s

K = 8 + 6 + 10

K = 24 cm

Semoga membantu ^_^
