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?
Answer & explanation
Correct answer: option 3
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
