Hey your answer is
-----------------------------

Let the radius be x meters

perimeter of the plot 2πx meters

Rate of fencing per meter is RS 15

Total cost of fencing is =3300

=>15×2×22/7×x=3300

=>30x=3300÷22/7

=>30x=3300×7/22

=>30x=150×7

=>x=35

•°•cost for fencing the plot at the rate of RS 100per sq /m.

=110×35×100

=RS 385000
