A path 5 m wide runs along inside a square park of side `100 m.` Find the area of the path. Also find the cost of cementing it at the rate of `Rs250` per `10m^2.`

Explanation

To solve the problem step by step, we can break it down as follows:

### Step 1: Determine the side length of the inner square park
The outer square park has a side length of 100 m. Since there is a path that is 5 m wide running along the inside of the square park, we need to subtract the width of the path from both sides of the square.

- **Calculation**:
\[
\text{Side of inner square} = \text{Side of outer square} - 2 \times \text{Width of path}
