Răspuns :
Fie a numarul merilor si b numarul perilor
a+b=441
b=6a
a+6a=441
7a=441
a=63(meri)
b=6a
b=6*63
b=378(peri)
a+b=441
b=6a
a+6a=441
7a=441
a=63(meri)
b=6a
b=6*63
b=378(peri)
meri 1 segment I-----I
peri 6 segmente I-----I-----I-----I-----I-----I------I
total = 7 segmente = 441
1 segment = 441 :7 = 63
deci : meri = 63
peri = 6 · 63 = 378
peri 6 segmente I-----I-----I-----I-----I-----I------I
total = 7 segmente = 441
1 segment = 441 :7 = 63
deci : meri = 63
peri = 6 · 63 = 378
