1 hectare=10000m^2
so 9 hectares =90000m^2
area=90000m^2
so side= rootunder90000=300m
perimeter =4×300=1200m
cost of one metere fencing =35rupees
hence cost of 1200m fencing =1200×35=42000rupees
so 9 hectares =90000m^2
area=90000m^2
so side= rootunder90000=300m
perimeter =4×300=1200m
cost of one metere fencing =35rupees
