Question

The cost of harvesting a square field at Rs.900 per hectare is Rs.8100. Find the cost of putting a fence around it at Rs.18 per meter.

Answer 1

1hectare =100meters
8100/900
=9hectares^2
90000m^2
s^2=90000
s=90000^1/2
s=300m
4*300m
1200*18
6*2*6*3*100
6*6*6*100
36*6*100
216*100
21600
cost of putting a fence around square field =Rs21600
