A) 650:5=130 ( latimea )
130x4=520 ( lungimea )
B) 100:5=20 ( latimea )
20x4=80 ( lungimea )
C) 340:5=68 ( latimea )
68x4=272 ( latimea )
2) 67dam=670m ( prima bucata )
670m-320m=350m sau 35dam( atat a mai ramas din prima bucata dupa ce s-au vandut 320m )
600m=60dam ( a doua bucata )
60dam-30dam=30dam sau 300m ( atat a mai ramas din a doua bucata )
35dam+30dam=65dam
350m+300m=650m
