Solution

  1. Length of boundary = 15 metre + 6 metre + 15 metre + 24 metre
    = 60 metre
  2. Boundary = 9 metre + 6 metre + 3 metre + 6 metre + 6 metre + 12 metre
    = 42 metre
  3. Boundary = 9 metre + 6 metre + 3 metre + 6 metre + 6 metre
    + 12 metre
    = 42 metre
  4. Boundary = 15 metre + 15 metre + 9 metre + 15 metre + 15 metre + 9 metre
    = 78 metre

Therefore, field (d) has the longest boundary.
