Question

Panjang sisi sisi sebuah segitiga 2x cm , (2x+2)cm dan (3x+1)cm tentukan panjang sisi sisi nya jika keliling nya 24 cm

Answer 1

Sisi segitiga ada 3 yaitu :
2x + (2x+2) + (3x+1) = 24
7x +3 = 24
7x = 21
x= 21/7 = 3

Sisi-sisinya :
2x = 2(3) = 6cm
2x+2= 2(3)+2 = 8cm
3x+1= 3(3)+1 = 10cm

Answer 2

Kell = a + b + c
24 = 2x + 2x + 2 + 3x + 1
24 = 7x + 3
24 -3 =7x
21 = 7x
x = 21/7
x= 3

a = 2x = 2(3)
= 6cm
b =2x+2 = 2(3) +2
= 8cm
c = 3x + 1 = 3(3) +1
= 10 cm
semoga membantu:)
