Answer:
 53 yards
Step-by-step explanation:
Let w represent the width. Then w+2 is the length, and the perimeter is ...
 P = 2(L+W) . . . . . . . . . formula for the perimeter of a rectangle
 216 = 2((w+2) +w) . . . . fill in values for length and width
 216 = 4w +4 . . . . . . simplify
 54 = w +1  . . . . . divide by 4
 53 = w . . . . . subtract 1
The width of the rectangle is 53 yards.
