Question

The cost of fencing a square field at 3.20 per m is
6400. Find the cost of levelling the field at 85 per are.​

Answer 1

Answer:

₹ 2125

Step-by-step explanation:

Rate of fencing = ₹ 3.20 /m

Total cost of fencing = ₹ 6400

Perimeter of sq. field = Total cost/rate

= 6400/3.20

= 2000 m

Perimeter of sq. field = 2000 m

each side = perimeter/4

= 2000/4

= 500 m

Area of sq. field = 500 × 500

= 250000 sq. m

10000 sq. m = 1 acre

250000 sq. m = 250000/10000

= 25 acre

Rate of leveling = ₹ 85 /acre

Cost of leveling 25 acre = 85 × 25

= ₹ 2125

Hence, Cost of leveling is ₹ 2125 .
