Question

the cost of fencing a square field at the rate of ₹16/m is ₹32000. find the cost of reaping at the rate of ₹35/100 per m square

Answer 1

Cost of fencing is- Rs.32000.
For 1m-Rs. 16.
So the total perimeter= 32000/16= 2000m.
Since it is a square, the length of one side= Perimeter/4
=2000/4=500m.
Area= l*l= 500*500=250000m^2.
Cost of reaping for 1 m= 35/100
For the complete field it would be=35/100*250000.
=Rs. 87500

Hope this helps u. :)
