The area of square field is 2025 m².  The breadth of a rectangular park is \(\frac{1}{3}\)rd of the side of the square field and its length is two times of its breadth.  What is the cost (in Rs) of leveling the park at Rs 29.5 per m²?

side of square (a) = \(\sqrt {2025}\) = 45 m²

Breadth of rectangle = \(\frac{1}{3}\) × 45 = 15 m

Length of rectangle = 15 × 2 = 30 m

Area of rectangular park  = 30 × 15 = 450 m²

Cost of leveling the park = 450 × 29.5 = Rs.13275
