Step-by-step explanation:

Each rectangle is a step. We'll start with the top one. This is simple: 6 times 3.

$6 * 3 = 18.$

The farthest left is 5 times 3.

$5 * 3 = 15.$

The crossed one is 6 times 5.

$6 * 5 = 30.$

The one to the right of the crossed one is 3 times 5, again.

$3 * 5 = 15.$

The farthest right is 6 times 5, again.

$6 * 5 = 30.$

The bottom one is 6 times 3, again.

$6 * 3 = 18.$

Now, we add.

$18 + 18 = 36.\\15 + 15 = 30.\\30 + 30 = 60.\\36 + 30 + 60 = 126.$

Burka [1]

Answer:

Step-by-step explanation:

chiều dài:x,x>0

chiều rộ:y

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

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

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

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

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

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

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