Răspuns:
P = 50 dam = 500 m
L = 15 dam = 150 m
l = 10 dam = 100 m
Explicație pas cu pas:
Pozitionarea stalpilor :
x x x x
x x
x x x x
Avem 10 stalpi si 10 intervale
1 interval = distanta dintre 2 stalpi = 5 dam =>
Perimetrul = 10 x 5 dam = 50 dam = 500 m
Lungimea are 3 intervale = 3 x 5 dam = 15 dam = 150 m
Latimea are 2 intervale = 2 x 5 dam = 10 dam = 100 m
P = 50 dam = 500 m
L = 15 dam = 150 m
l = 10 dam = 100 m
