Answer 2

Answer:

length= 35m

breadth= 50m

to find the fencing needed we need to find perimeter

perimeter of rectangular back yard= 2*(l+b)

                                                         = 2*(35+50)m

                                                         = 2*85m

                                                         =170m

he will need 170m of fecing to enclose his yard.

cost of fencing one m= $45

then cost of fencing the whole back yard= 45*170

                                                                    =$7650
