Question

Lungime a unui dreptunghi e 96 de pasi iar latime 84 pasi cit va fi perimetrul daca a) 6 pasi = 4m b) 8 pasi = 6m

Answer 1

P=2(L+l)
P=2(96+84)=360:6=60x4=240 m
P=2(96+84)=360:8=45x6=270 m

Answer 2

P= 2×l+2+L
a) 96÷6=16
16×4=64
84÷6=14
14×4=56
P=240m
b) 96÷8=12
12×6=72
84÷8=10.5
10.5× 6=63
P= 270
