उत्तर
- Length of boundary = 15 metre + 6 metre + 15 metre + 24 metre
= 60 metre - Boundary = 9 metre + 6 metre + 3 metre + 6 metre + 6 metre + 12 metre
= 42 metre - Boundary = 9 metre + 6 metre + 3 metre + 6 metre + 6 metre
+ 12 metre
= 42 metre - Boundary = 15 metre + 15 metre + 9 metre + 15 metre + 15 metre + 9 metre
= 78 metre
Therefore, field (d) has the longest boundary.
