Răspuns:
A ______ + 20 dm + 4 m
B ______ + 20 dm
C ______
L = 7200 cm = 72 m
3 segmente + 20 dm + 4 m + 20 dm = 72 m
3 segmente + 2 m + 4 m + 2 m = 72 m
3 segmente = 72 m - 8 m = 64 m
1 segment = 64 : 3 = 21,33 m
C = 21,33 m (a treia parte)
B = 21,33 + 2 = 23,33 m (a doua parte)
A = 21,33 + 6 = 27,33 m (prima parte)
