sides of a rectangular park are in the ratio 2 : 5 and its area is 3750 sq m , the cost of fencing it at 50 ps per meter is ?
"2 x * 5 x = 3750 = > x = 19.36 2 ( 80.64 + 50 ) = 261.28 m 261.28 * 1 / 2 = rs . 130.64 answer : e"
divide(multiply(50, rectangle_perimeter(sqrt(divide(multiply(3750, 5), 2)), divide(3750, sqrt(divide(multiply(3750, 5), 2))))), const_100)
