Answer:
Length in feet is equal to 
, where P is the perimeter
Step-by-step explanation:
Let the width (W) of the yard be "X"
Then the length(L) of the yard will be
The perimeter of the yard will be equal to the sum of twice the length and width of the yard
Thus,
Substituting the given values in above equation, we get -
Thus, width in terms of perimeter is equal to
Length in feet is equal to
