Explanation:

- The cost of gardening the circle is Rs 3465 at a rate of Rs 10 per square meter.

- Therefore, the area of the circle can be calculated as: Area = Rs 3465 / Rs 10/m² = 346.5 m².

- Using the formula for the area of a circle, A = pr², we solve for r:

r² = A / p = 346.5 / 3.14 ˜ 110.35

r ˜ 10.5 m.

- The diameter of the circle is twice the radius: Diameter = 2 × 10.5 = 21 m.

- The side of the square is equal to the diameter of 21 m.

- The perimeter of a square is calculated as 4 × side:

Perimeter = 4 × 21 m = 84 m.

- Correct Answer: Option 2 - 84 m
