Answer 2

The cost will be 112500rupees.

Given data :

At the rate of rupees 27.50 per square metre we can complete the fencing job in rupees 55000.

So,

27.50 rupees = 1 m

1 rupee = (1/27.50) m

55000 rupees = (55000/27.50) = 2000m.

So perimeter of the field = 2000m

One side length = (2000÷4) = 500m

Area = (500×500)m² = ₹250000

Now,at the rate of ₹45/100m²,the reaping job will cost

100 m²= 45 rupees

1 m² = 45/100 rupees

250000 m²= 45×250000/100 =112500 rupees. (Answer)
