Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e 5880
The area of a square shaped field is 1764 m2
a2 = 1764
a = 42 m
The breadth of rectangular park = (1/6) × 42 = 7 m
The length of the rectangular park = 4 × 7 =28 m
The area of the rectangular park = 7 × 28 = 196 m2
The cost (in ₹) of levelling the park at ₹30 per m2 = 196 × 30 = ₹ 5880
