1. Answer:

   Cost of levelling =Rs.15 per square meter

   Let A be the area of lawn.

   Therefore,

   Cost of levelling lawn =15×A=Rs.19,935(Given)

   ⇒A=

   15

   19935

   =1329m

   2

   As we know that,

   Area of square =a

   2

   Here a is the edge length of square.

   Since, lawn is in square form.

   Therefore,

   Side length of square (a)=

   A

   =

   1329

   =36.45m

   Perimeter of square =4a=4×36.45=145.82m

   Now,

   Cost of fencing =Rs.22 per meter

   Therefore,

   Cost of fencing lawn =22×145.82≈Rs.3208
