sides of a rectangular park are in the ratio 4 : 3 and its area is 3750 sq m , the cost of fencing it at 50 ps per meter is ?
"4 x * 3 x = 3750 = > x = 17.7 2 ( 82.3 + 50 ) = 264.6 m 264.6 * 1 / 2 = rs . 132.3 answer : a"
divide(multiply(50, rectangle_perimeter(sqrt(divide(multiply(3750, 3), 4)), divide(3750, sqrt(divide(multiply(3750, 3), 4))))), const_100)
