Burka [1]

Answer:

Step-by-step explanation:

chiều dài:x,x>0

chiều   rộ:y

\left \{ {({x+y)*2=326} \atop {xy=6370}} \right.

\left \{ {{x+y=163} \atop {xy=6370}} \right.

\left \{ {{y=163-x} \atop {xy=6370}} \right.

\left \{ {{y=163-x} \atop {x*(163-x)=6370}} \right.

\left \{ {{y=163-x} \atop {163x-x^{2} =6370}} \right. \\

\left \{ {{y=163-x} \atop {x_{1} =98; x_{2} =65}} \right.

\left \{ {{y=65} \atop {x=98}} \right.
