______Answer ________
Let us divide question in 2 parts
1. Cost of leveling:-
Length of field,l=38.50m or 38.5m
Breadth of field,b=61.50m or 61.5m
Area of rectangular field
=l×b
=38.5m×61.5m
=2367.75m square
Cost of leveling 1 m square= RS.40
Cost of leveling 2367.75 square
=Rs40×2367.75
=94,710/-
2.for running 2km rounds required
=2Km or 2000m/perimeter of rectangular field
=2000m/2(l+b)
=2000m/2(38.5m+61.5m)
=2000m/2(100m)
=2000m/200m
=10
Therefore,20 rounds should be taken to run 2km
