Question

calculati perimetrul si aria unui patrat cu latura de un intreg si 3 pe 5 metri

Answer 1

1INTREG3/5=8/5 M=1,6 M
PERIMETRUL=4XL=4X1,6=6,4 M
ARIA=LATURA^2=1,6^2=2,56 M^2

Answer 2

[tex]L=1 \frac{3}{5} m.\\ A_A_B_C=l^2=\ \textgreater \ 1,6m^2=\ \textgreater \ 2,56m^2\\ P_A_B_C=4l=\ \textgreater \ 1,6*4=6,4m[/tex][tex]II:L=1 \frac{3}{5} m\\\\ A_A_B_C=L^2=\ \textgreater \ (\frac{8}{5} ^2)^2=\ \textgreater \ \frac{64}{25} m^2\\\\ P_A_B_C=l*4=\ \textgreater \ \frac{8}{5} *4= \frac{32}{5} m[/tex]
