The area of the lawn is 19935/15 = 1329 sqr meter.
Hence length of a side of the square lawn, A = sqroot(1329) meter=36.46 meter
To fence the lawn means to fence the perimeter of the lawn of square size.
Perimeter of the Lawn, 4*A meter
Cost to fence the lawn = Perimeter * 22 rupees. = 4 * 36.46 * 22 rupees = 3208.48 rupees
