Berat badan Dirza =30((64:2)-2)
Berat badan Dayla = 52(30+22)
Berat badan Dirza dan Dayla = 30+52=82kg
2. Kebun Eyang = 500
1 pohon = 5
Kebun Yang dipenuhi pohon= 500:5=
100
Total pohon dikebun 100 pohon.
ditebang 70
jadi pohon sisanya adalah 100-70=30
berat dayla = 64+22kg = 86
berat dirza = 1/2 x 64 (-2) = 30
jadi berat dayla dan dirza = 86 + 30 = 116kg.
2). banyak pohon yg di tanam = 500/5 = 100.
sisa pohon di kebun = 100 - (50+20)
= 100 - 70
=30,jadi sisa pohon dikebun ada 30%.
