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
