Step-by-step explanation:
The question in English is
The given figure is made up of 6 identical squares.The perimeter of the figure is 126 cm.what is the length of each side of square?
The picture of the question in the attached figure
Let
x ----> the length side of each square
we know that
The perimeter is the sum of the borders of the figure
so
In this problem
[tex]P=14x[/tex]
see the attached figure N 2 to better understand the problem
we have
[tex]P=126\ cm[/tex]
so
[tex]14x=126[/tex]
solve for x
[tex]x=9\ cm[/tex]
therefore
The length of each side of square is 9 cm
