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 rum 2km
