Answer:

cost to fence =$1600

cost to fence per m=$25

length=20m

breadth=?

=1600/25=64

=p=2(l+b)

64=2(20+ b)

=20+b=64/2=32

b=32-20=12

b=12

Answer:12

Step-by-step explanation:25[2(l+b)]=1600  [perimter *25 =cost]

                                           

                                              2(l+b)=1600/25

                                                 2(20+b)=64

                                                    20+b=32

                                                        b=32-20

                                                        b=12
