latimea (l) I-----------------I
lungimea (L) I-----------------I-------I
↓ ↓
latimea +5
P = l +l + L +L
P I-----------------I-----------------I-----------------I-------I-----------------I-------I 50
latime latime latime 5 latime 5
sunt 4 segmente egale care reprezinta latimea
50 -(5+5) = 50-10 =40
40 :4 = 10
latimea = 10 m
Lungimea = 10 + 5 = 15 m
