Answer:
Step-by-step explanation:
Perimeter equals the lengths of each side or edge added together
The perimeter of a square is P = 4 × side   all four sides ar the same length
The perimeter of a rectangle is P = 2×L + 2×W
Perimeter of a circle is P = π × r
The perimeter here is a random polygon, but still just add up all sides to get your answer.
P = 47 + 50 + 9 + 30 + 30 + 30 + 9 +50
 = 47 + 2×50 + 2×9 + 3×30
 = 47 + 100 + 18 + 90
  = 190 + 65
P = 255 yards    I assume there is a typo somewhere in the question
