Answer 2

Answer:

given :

l = 108 m

b = 55 m

rate of fence = rs 12

Step-by step explanation:

now total wire  needed  to  fence the field = perimeter of rectangle

                                                                      = 2 ( l + b )

                                                                      =  2 ( 108 + 55 )

                                                                      = 2 * 163

                                                                       =  226 m

cost of 1 m fence = 12 rs

cost of 226 m fence = 12 * 226 = Rs 2712
