Question

lungimea unei livezi are 56m,iar latimea de 7 ori mai mica.afla perimetrul livezii.

Answer 1

$L=56 \ m \\ l=\frac{L}{7} =\frac{56 \ m}{7} \\ l=8 \ m \\ P=2L+2l=2(L+l) \\ P=2(56 \ m+8 \ m) \\ P=2 \cdot 64 \ m \\ \Rightarrow \boxed{\bold{P=128 \ m}}$

Answer 2

56m:4=6m (latimea)
56x2+6x2=112+12=124
