1. **Problem:** Athul walked along the outer edge of a rectangular park with length 30 m and width 23 m. Find the total distance he walked, which is the perimeter of the rectangle. 2. **Formula:** The perimeter $P$ of a rectangle is given by: $$P = 2(\text{length} + \text{width})$$ 3. **Calculation:** Substitute the given values: $$P = 2(30 + 23)$$ $$P = 2(53)$$ $$P = 106$$ 4. **Explanation:** The perimeter is the total distance around the rectangle. Adding length and width gives the sum of two adjacent sides, and multiplying by 2 accounts for all four sides. 5. **Answer:** The total distance Athul walked is **106 m**. **Final answer:** B) 106 m
