Find the cost of fencing a square park of side 250 m at the rate of Rs. 20 per metre.

Answer

To find the cost of fencing a square park with a side of 250 meters at the rate of Rs. 20 per meter, we can follow these steps:

### Step 1: Calculate the Perimeter of the Square Park
The formula for the perimeter (P) of a square is given by:
\[ P = 4 \times \text{side} \]

Given that the side of the park is 250 meters, we can substitute this value into the formula:
\[ P = 4 \times 250 \]

### Step 2: Perform the Multiplication
Now, we need to calculate:
\[ P = 4 \times 250 = 1000 \text{ meters} \]

### Step 3: Determine the Cost of Fencing
The cost of fencing is calculated by multiplying the total perimeter by the cost per meter. The cost per meter is given as Rs. 20. Therefore, we calculate the total cost (C) as follows:
\[ C = \text{Perimeter} \times \text{Cost per meter} \]
\[ C = 1000 \times 20 \]

### Step 4: Perform the Multiplication for Cost
Now, we calculate:
\[ C = 1000 \times 20 = 20000 \text{ Rupees} \]

### Final Answer
The total cost of fencing the square park is Rs. 20,000.
