Question

The cost of levelling a square lawn at ₹2.50 per sq. m is ₹13322.50.find the cost of fencing it at ₹5 per

Answer 1

Area of square lawn = total amt / cost per sq m
                                 = 13322.50/2.50 = 5329m²
Area of square , a²= 5329 ⇒ a = 73
Cost of fencing = perimeter of the square lawn * 5
                          = (4 *73) *5
                          =Rs.1460




Hope it helps.... :)

Answer 2

Answer:

Rs.1460

Step-by-step explanation:

Given

Rate = Rs 2.50 per metre square

Total Cost= Rs 13322.50

Sol:-

Area= Total cost /Rate

=13322.50/2.50

= 5329

Area =5329

Side × Side = 5329

$(side) {}^{2} = 5329$

$side = \sqrt{5329}$

$side = 73$

Perimeter = 4 × Side

= 4× 73

= 292

Cost of fencing = 292 × 5

= Rs 1460
