Answer 2

$\huge\green{\fbox{ʂσʅυƚiσɳ}}$

Total cost of fencing square park = Rs. 5062.50

Rate of fencing = Rs. 22.50/meter

So the total lenght of the fencing

= 5062.50/22.50

= 225 m.

Which is equal to the perimeter of the park.

We know the perimeter of a square

= 4×side

225=4×side

Side = 225/4=56.25 m.

56.25 m is the lenght of each sides of the square park.
