1. Jawaban :
Dik: segitiga a Dik: segitiga b
a = x cm a = 12cm
b = 2p cm
b = 2x cm
c = 3p cm
c = 9 cm K = 52 cm
K = 30 cm Dit:
Berapa nilai p?
Dit:
Jawab:
Berapa nilai x?
K=a+b+c
Jawab:
52 = 12 + 2p + 3p
K= a + b + c
52 = 12 + 5p
30 = x + 2x + 9
52 – 12 = 5p
30 = 3x + 9
40 = 5p
30 – 9 = 3x
8 =p
21 = 3x
7=x
