Va rog , rapid corect si complet iar raspunsul va fi recompensat ​

Answer 1

Răspuns:

L=24 m

l=5L/6=5×24/6=5×4=20cm

a)L/l=24/20=6/5

b) l/L=5/6

c) P/L=2(L+l)/L=2+2l/L=2+2×5/6=2+5/6=2+5/3=11/3

d) l/L=l/(2l+2L) =20/2(20+24) =20/2×44=5/22

Answer 2

$\frac{6}{5}$Răspuns:

Deci, in primul rand, spune ca L=24 cm, l=$\frac{5L}{6}$, introducem L.

l=$\frac{5*24}{6}$, simplificam, 24 și 6 se taie și ramane 5*4= 20

Rezolvare:

a)

[tex]\frac{L}{l\\ } [/tex]=$\frac{24}{20}$=$\frac{6}{5}$

b)$\frac{l}{L} =\frac{20}{24} =\frac{5}{6}$

c)$\frac{P(perimetru)}{L(lungime}=\frac{2*(L+l)}{L} =\frac{2+2l}{L} =\frac{2+2*5}{6} =\frac{2*5}{3} =\frac{10}{3}$

d)$\frac{l}{P}=\frac{l}{(2l+2L)}=\frac{20}{2*(20+24)} =\frac{20}{2*44} =\frac{5}{22}$
