AS3 Dropped MovieClip doesn't take parent's dimensions

Question

Please help me with my code. I'm working on a map project with several movie clips that are dragged and dropped onto their respective movie clips.
PROBLEM:
Initially, draggable movie clips are reduced their original size. When they are dropped onto their matching movie clip, I would like them to take the dimensions of the movies placed on the map. How to do that?
HERE IS MY CODE
stop();
var startX:Number;
var startY:Number;
var finalX:Number;
var finalY:Number;
var finalWidth:Number;
var finalHeight:Number;
var counter:Number = 0;
alta_mc1.addEventListener(MouseEvent.MOUSE_DOWN, pickUp);
alta_mc1.addEventListener(MouseEvent.MOUSE_UP, dropIt);
alta_mc3.addEventListener(MouseEvent.MOUSE_DOWN, pickUp);
alta_mc3.addEventListener(MouseEvent.MOUSE_UP, dropIt);

alta_mc2.addEventListener(MouseEvent.MOUSE_UP, dropIt);
