We will be using the formula for the perimeter of a square which is 4 times its side. Side of the square park = 250 m The perimeter of the park = 4 × side ⇒ 4 × 250 = 1000 m 1000 m is the perimeter of the square park. Now, the cost of 1 m fencing is ₹ 20 Hence, the cost of 1000 m fencing = ₹ 20 × 1000 = ₹ 20,000 Therefore, ₹ 20,000 is the cost of fencing a square park of side 250 m at the rate of ₹ 20 per metre.
TIP - WHEN THE QUESTION SAYS FENCING FIND OUT THE PERIMETER BUT WHEN THE QUESTION SAYS TILLING FIND OUT THE AREA. FENCING MEANS BORDER WHILE TILLING MEANS THE WHOLE AREA INCLUDING THE CENTRE.

Side of the square park = 250 m
The perimeter of the park = 4 × side
⇒ 4 × 250 = 1000 m
1000 m is the perimeter of the square park.
Now, the cost of 1 m fencing is ₹ 20
Hence, the cost of 1000 m fencing = ₹ 20 × 1000 = ₹ 20,000
Therefore, ₹ 20,000 is the cost of fencing a square park of side 250 m at the rate of ₹ 20 per metre.
