sides of a rectangular park are in the ratio 3 : 2 and its area is 2400 sq m , the cost of fencing it at 50 ps per meter is ?
"3 x * 2 x = 2400 = > x = 20 2 ( 60 + 40 ) = 200 m 200 * 1 / 2 = rs . 100 answer : b"
divide(multiply(50, rectangle_perimeter(sqrt(divide(multiply(2400, 2), 3)), divide(2400, sqrt(divide(multiply(2400, 2), 3))))), const_100)
