Penjelasan dengan langkah-langkah:
PQ = SR
2p + 9 = 4p + 3
4p-2p = 9- 3
2p = 6
p= 3
maka nilai p = 3 cm
b) panjang PQ = 2p + 9
PQ= 2(3) + 9
PQ = 15 cm
c) keliling = 2(panjang + lebar )
Keliling = 2 ( 15 + 10 )
keliling = 2 (25)
keliling = 50 cm
d) Luas = panjang x lebar
Luas = 15 cm x 10 cm
Luas = 150 cm2
