Answer 1

Step-by-step explanation:

Length= 40m

Width = 25m

Area of outer rectangular feild = l×b=

40×25

=1000m^2

Length inner rectangle 40-2-2=36

Width of inner rectangle 25-2-2=21

Area of inner rectangle l×b

36×21=756

Area of path =Area of outer rectangle -Area of inner reactangle=1000-756=

244

Cost of travelling =Area×Rate=244×2.5= 610m^2
