The cost for enclosing a rectangular garden with a fence = 5400 RS 
The perimeter of the rectangle = 2(l+b)
Length of the rectangle(l) = 100 m
Rate of fencing per metre = 15 RS
Therefore 2(l+b)*15=5400
100+b = 5400/30 = 180
breadth (b) = 180 - 100 = 80 m .
Area of the rectangle = l*b = 100*80 = 8000 square metres.
