the cost of levelling a square lawn at Rs. 15 per square meter is Rs. 19935. Find the cost of fencing the lawn at Rs. 22 per meter

Answer 1

Area=19935/15=1329
Area =side *side
square root of 1329=s
S=36.45
P=36.45*4=145.8
Cost of fencing =145.8*22
=3207.6

Answer 2

₹15 = 1 m²

₹19935 = (19935/15) m²

Area of square = 1329 m²

Area of square = 1329 m²

Side of square = √1329 m

Side of square = 36.4 m

Perimeter of square = 4 × Side

Perimeter of square = 4 × 36.4

Perimeter of square = 145.6 m

Cost of fencing 1 m = ₹22

Cost of fencing 145.6 m = ₹(145.6 × 22)

Cost of fencing 145.6 m = ₹3203.2
