Question

Un dreptunghi are lungimea de 24 cm si latimea 6cm.
a.Calculati perimetrul si aria.
b.Calculati perimetrul patratului cu aceeasi arie ca dreptunghiul.

Answer 1

P=2(l+L)=60 CM
A=L*l = 24*6=144 CM
b) Nu inteleg cerinta la b..nu are logica

Answer 2

$L_d=24 \ cm \\ l_d=6 \ cm \\ P_d=2L+2l \\ P_d=2*24 \ cm+2*6 \ cm \\ P_d=48 \ cm+12 \ cm \\ \boxed{P_d=60 \ cm} \\ A_d=L*l \\ A_d=24 \ cm*6 \ cm \\ \boxed{A_d=144 \ cm^2} \\ A_p=l^2 \\ A_p=144 \ cm^2 \\ l_p= \sqrt{144} \\ l_p=12 \ cm \\ P_p=4l \\ P_p=4*12 \ cm \\ \boxed{P_p=48 \ cm}$
