Answer 2

Answer:

6. total cost to fence = $1600

   rate of fencing = $25 per m²

   let breath be X

   area of field = lenght × breath

                        = 20m × Xm

                        = 20Xm²

   area of field × rate of fencing = total cost of fencing

   20X × 25 = 1600

   X =  1600  

        20 × 25

     = 3.2m

   Perimeter = 2 ( 20 + 3.2 )

                    = 2 × 23.2

                    = 46.4m

7. Sorry bro I am unable to do this one.
