Answer 1

Step-by-step explanation:

Given

Cost of fencing the square field at Rs. 7.80 per metre =Rs.936

So, total length of fence =

7.80

936

=120

Thus, the perimeter of the field =120 m

⇒4× side =120 m

⇒ side =

4

120

=30 m

∴ Area of square field =(30)

2

=900m

Hence, Cost of levelling the field =900×2.50=Rs.22.50
