sides of a rectangular park are in the ratio 3 : 2 and its area is 3750 sq m , the cost of fencing it at 20 ps per meter is ?
"3 x * 2 x = 3750 = > x = 25 2 ( 75 + 20 ) = 190 m 190 * 1 / 2 = rs . 95 answer : d"
divide(multiply(20, rectangle_perimeter(sqrt(divide(multiply(3750, 2), 3)), divide(3750, sqrt(divide(multiply(3750, 2), 3))))), const_100)
