Perimetrul dreptunghiului =P
latimea =l
Lungimea =L
l=L/2
P=2 [L+l] =300=2(L/2+L)=300=L+2l=300=3L=L=100 m (metri )
l=100/2=L=50
R-l=>50
-L=100
latimea =l
Lungimea =L
l=L/2
P=2 [L+l] =300=2(L/2+L)=300=L+2l=300=3L=L=100 m (metri )
l=100/2=L=50
R-l=>50
-L=100
l=latimea si L=lungimea =2*l
2*{2*l+l)\320
6*l=320
l = 320:6 =160/3
L=2*160/3=320/3=10,(6) m
2*{2*l+l)\320
6*l=320
l = 320:6 =160/3
L=2*160/3=320/3=10,(6) m
