sides of a rectangular park are in the ratio 3 : 2 and its area is 7350 sq m , the cost of fencing it at 50 ps per meter is ?
"3 x * 2 x = 7350 = > x = 35 2 ( 105 + 70 ) = 350 m 350 * 1 / 2 = rs . 175 answer : e"
divide(multiply(50, rectangle_perimeter(sqrt(divide(multiply(7350, 2), 3)), divide(7350, sqrt(divide(multiply(7350, 2), 3))))), const_100)
