Answer 2

$\huge{\colorbox{aqua}{Solution}}↓$

Length of one side = 250 m

To calculate the cost of fencing, we require perimeter.

Perimeter of the square park :

$\begin{gathered}4 × length \: of \: a \: side \\ = 4 × 250m \\ = 1000m\end{gathered}$

Cost of fencing 1 m of park = Rs.20

$\therefore$ The total cost of fencing the park = Rs.20 × 1000 = Rs.20000
