Detailed Solution

Concept-We've done that;

65536 m^{2}

is the square field's area.
The square's area is equal to the side.
If "a" represents the square's side, then

a = 65536, a \times a = 65536, a = 65536 and a = 256 . So, the square' s side is 256 metres .

We must now determine the square's perimeter. The square's perimeter is the sum of the lengths of its borders. Considering that a square has four equal-length sides,
square perimeter equals four sides
Square's side is

256 metres .

Therefore, the square's perimeter is

4 \times 256, which equals 1024 .

The square's perimeter is

1024 m .

We can now determine how much it will cost to fence the field. We stated that a 1 m fence would cost 5 Rs.
Cost of fencing the boundaries is therefore equal to perimeter
