perimeter of square field=total cost/rate of fencing
4 x side length=32000/16
4 x side length=2000
hence side length=500 m
now area of square field=(side length)^2
=(500)^2
=250000 m^2
cost of reaping the field=rate of reaping x area of square field
=35/100 x250000
=35 x 2500=87500 Rs

Answer:
Step-by-step explanation:
Perimeter of field= total cost÷ rate
=32000÷16
=2000m
Side of field =perimeter/4
=2000/4
=500m
Area of field = side× side
= 500m X 500m
=250000 sq m
Cost of repairing 100 sq m = Rs 35
Cost of repairing 1 sq m. =
Rs35/100
Cost of repairing the field =
35×250000/100
=Rs 87500
