Q. 22

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 metre.

Given:

Rate = Rs 900 per hectare

Total Cost = Rs 8100

Rate of fencing = Rs 18 per metre

Let the side of square field be s

Now,

= 9 hectares = 90000 m2

Area = side2

90000 m2 = side2

side = 300 m2

Now,

Perimeter = 4 × side

= 4 × 300 m2

= 1200m2

Therefore,

Cost of fencing = 1200 m2 × Rs 18 per metre

= Rs 21600
