Given:
Rate=Rs 8.50 per sq m
Total Cost= Rs 2750
Rate of fencing along the boundary=Rs 11.50 per m
Step-by-step explanation:
We know that Total cost/ Rate=Area
Area=2750/8.5
On calculating Area= 323.5 sq m.
But Area of Square= (side)^2 = 323.5
side=√323.5
side=17.9 m
Perimeter = 4× side
Perimeter=4×17.9=71.6m
Total Cost =Rate× Perimeter
Total Cost=Rs(11.50×71.6)
Total Cost = Rs 823.5
