Answer:
Step-by-step explanation:
cost of harvesting a square field=rs1620
cost ..........................1hectare..........=rs 180
area of field=1620/180= 9hectare
1 hectare=10000m^2
so, area=90000m2
a*a=90000
a^2=90000
a =√90000
a =300m
perimeter=4*a
=4*300
=1200m
cost of fencing 1m=rs6.75
cost of fencing 1200m=rs.1200*6.75
=rs.7100
