Rumus Luas Segitiga Dan Keliling Segitiga

Rumus Luas Segitiga Untuk mencari luas sebuah segitiga kita gunakan rumus sebagai berikut :

Luas Segitiga =

1 / 2

x bantalan x tinggi

Contoh Soal
Hitunglah luas segitiga jika panjang alasnya 5 cm dan tingginya 4 cm ? Pembahasan alas = 5 cm
tinggi = 4 cm

Luas Segitiga =

1 / 2

x bantalan x tinggi
Luas Segitiga =

1 / 2

x 5 x 4
Luas Segitiga = 10 cm²

Rumus Keliling Segitiga Apabila kita hendak mencari keliling segitiga, maka rumus yang digunakan yakni :

Keliling Segitiga = Sisia a + Sisi b + Sisi c

Contoh Soal
Sebuah lapangan berbentuk segitiga dengan panjang sisi-sisinya 25 m, 35 m, dan 40 m . Berapakah keliling lapangan tersebut ? Pembahasan Keliling Lapangan = 25 + 35 + 40
Keliling Lapangan = 100 cm² Untuk menyaksikan latihan-latihan soal luas segitiga dan keliling segitiga yang lebih banyak lagi, silahkan kunjungi panduan berikut ini :
