sides of a rectangular park are in the ratio 3 : 2 and its area is 1536 sq m , the cost of fencing it at 50 ps per meter is ?
"3 x * 2 x = 1536 = > x = 16 2 ( 48 + 32 ) = 102 m 102 * 1 / 2 = rs . 51 answer : a"
divide(multiply(50, rectangle_perimeter(sqrt(divide(multiply(1536, 2), 3)), divide(1536, sqrt(divide(multiply(1536, 2), 3))))), const_100)
