3x - drugi bok
2x + 6x = 8x
8x- obwód
9608cm - obwód
8x = 9608 cm / :8
x = 1201 cm
3x = 3603
ODP: Jeden bok ma 1201 cm, a drugi 3603 cm
obwód=2a+2b
a=1 bok
b=3a
2a+2×3a=96,08dm
2a+6a=96,08dm

a=96,08:8
a=12,01dm
b=3a=3×12,01dm=36,03dm
spr.2a+2b=96,08
2×12,01+2×36,03=96,08dm
24,02+72,06=96,08dm
II bok- x3
ilosc bokow- 4 w tym dwa po x kazdy i dwa po 3x kazdy
