Question

the cost of laying grass is ₹2754 at the rate of ₹8.50 per square metre in a square lawn. find how much it would cost to erect a fence along its boundary at ₹11.50 per metre​

Answer 1

Answer:

Rs. 3726/-

Step-by-step explanation:

PART 1

area of square lawn * cost per metre = Total cost

s² * 8.50 = 2754

s² = 2754/8.50

s² = 324 [ Area of square lawn]

∴ s = √324

∴ s = 18 m [ Side of square lawn]

PART 2

Cost of fencing per meter = Rs. 11.50

Cost of fencing 324 m = 324 * 11.50

                                      = Rs. 3726/-
