sides of a rectangular park are in the ratio 3 : 2 and its area is 3750 sq m , the cost of fencing it at 40 ps per meter is ?
"3 x * 2 x = 3750 = > x = 25 2 ( 75 + 50 ) = 250 m 250 * 0.40 = rs . 100 answer : c"
divide(multiply(40, rectangle_perimeter(sqrt(divide(multiply(3750, 2), 3)), divide(3750, sqrt(divide(multiply(3750, 2), 3))))), const_100)
