Let
x---------> the length of each side of the original garden
we know that
The area of the square is equal to
[tex] A= b^{2}[/tex]
where
b is the length side of the square
in this problem
[tex] b=(x+7)\ m\\ A=(x+7)^{2}\\A=169\ m^{2}[/tex]
so
[tex] (x+7)^{2}=169\\x+7=13\\ x=13-7\\x= 6\ m[/tex]
therefore
the answer is
the length of each side of the original garden is [tex] 6\ m [/tex]
