Question

The cost of levelling a square lawn at rupees 2.50 per square metre is rupees 17640 find the cost of fencing at rupees 5 per metre

Answer 1

Answer:

Cost of Fencing = Rs.1680

Step-by-step explanation:

Cost of leveling = 17640

Cost = Area * Rate

17640 = Area * 2.50

Therefore,

Area = 17640 / 2.50

Area of square lawn = 7056

Area of  square lawn = ( side )² = 7056 = 84

Therefore,

Side of lawn = 84 m

To find the perimeter,

Perimeter of square lawn = 4*side  = 4 * 84 = 336 m

Therefore,

Cost of fencing = 336*5 = Rs. 1680
