Radius of the garden= 56m
Circumference of the garden = 2×22/7×56= 352m
Cost of fencing for 1m=Rs.40
Cost of fencing for one round= 352×40= Rs.14,080
Cost of fencing for four rounds= 14080×4= Rs.56,320
So the final answer is 56,320 Rs.
Hope it helps...!!!

Answer:
The Total cost of fencing is 56,268.8 Rs.
Step-by-step explanation:
The radius = 56m
The Perimeter of the garden =2πr=2π×56
Perimeter =112πm
∴for four rounds =112π×4 =448πm.
Cost of fencing =40 Rs/m
The Total cost of fencing =40×448π
=17920πRs.
=56,267.8 Rs.
The Total cost of fencing is 56,268.8 Rs.
