Problem: sides of a rectangular park are in the ratio 3 : 2 and its area is 2460 sq m , the cost of fencing it at 50 ps per meter is ?
Rationale: "3 x * 2 x = 2460 = > x = 20.24 2 ( 79.76 + 50 ) = 259.52 m 259.52 * 1 / 2 = rs . 129.76 answer : c"
annotated_formula: divide(multiply(50, rectangle_perimeter(sqrt(divide(multiply(2460, 2), 3)), divide(2460, sqrt(divide(multiply(2460, 2), 3))))), const_100)
