Answer 2

Answer:

wire needed for fencing= 72m

cost of fencing the field = Rs 216

Step-by-step explanation:

Perimeter of field = length of wire required for fencing

(since u've not mentioned the shape of the field so i guess by dimensions its a rectangular field...)

Therefore, Perimeter of Field= 2 X ( l + b )

                                                = 2 X ( 36 )

                  Perimeter of Field= 72m

Therefore the cost of the field ( 3 per m ) = 72m X 3 = Rs 216
