The perimeter of the garden is [tex]220\ ft[/tex]
The width of the garden is [tex]50\ ft[/tex]
Suppose the length of the garden is [tex]x[/tex]
Perimeter is the sum of the lengths of the sides
[tex]\Rightarrow 220=2(x+50)\\\Rightarrow 110=x+50\\\Rightarrow x=60\ ft[/tex]
So, the length of the garden is [tex]60\ ft[/tex]
