To scale an object with the mouse: Select an object with the Object tool and drag one of its size handles. Hold down Shift to constrain scaling to the object's current aspect ratio. If Snap-to-Grid or Snap-to-Guides are selected in the Layout menu, the object will be aligned with the closest grid point or guides. To scale multiple objects, select all of them and then drag any of their size handles.

If you scale anobject which has the Proportional Scaling option selected, you will only be able to resize the selected object proportionally unless holding down the shift key.

Only the object's bounding box will be displayed if you drag without pausing. This is the best way to scale complex objects. To see the object's outline, hold down the mouse button and wait until the pointer changes to a two-way arrow before moving the mouse.

To scale an object with the Edit palette: Enter new width and height coordinates, or multiple or divide the current coordinates by the the scale factor. For example, enter 3.87cm*.5 or 3.87cm/2 to scale an object by 50% when the current value is 3.87cm.
