In a group of rectangles with fixed area, when one side of the rectangle is 6cm long and the other side is 8cm long, let x (CM) and Y (CM) be the two sides of the rectangle respectively [(1) find the analytic expression of the function of Y with respect to X. is this function an inverse scale function? If so, please point out the practical significance of the scale coefficient.] otherwise, I won't. [(2) in a rectangle, if the ratio of the two sides of a rectangle is 3:1, what is the perimeter of the rectangle?] otherwise, I won't]

Because the area is length multiplied by width, that is, xy = area, the fixed value of area is transformed into y = area / x, which is an inverse proportional function. As for the meaning, x, y must be greater than 0.2. If the ratio is 3:1, then x: y = 3 and xy = 48 solve the equations together, and the circumference is 32
