How to expand a rectangle only on 1 side?

Sorry for asking this but I don't know how to expand a rectangle just on one side, if I use ctrl t to expand it, it becomes bigger everywhere. I attached a video showing this. I just want to make the rectangle wider.

Ctrl+T to Transform. 

Hold down the Shift key while dragging edges.

Nancy’s Shift-drag tip works great if you want to temporarily disable proportional scaling. You can also turn off the Link Shape Width and Height link icon up in the options bar, which lets you disable or enable proportional scaling whenever you want.

But isn't there a way that the box around your rectangle follows it when you rotate it because now when I expand it using shift + drag this just happens: (check the video) I just want to make the rectangle higher like you would in a program like google docs or something.

Basically I just want to do this with the rectangle:

If you are working with a rastor layer, and not a live shape:

Use the ruler tool and run it along the edge of your slanted rectangle.

Make a note of the angle. In this case 30°

Click on Straighten

Use Free Transform to increase its height.

Use Free Transform again to rotate back using the pre noted angle.

Or, assuming that you iinittially created the rectangle perpendicular to the document boundary, before you do anything else, make it a Smart Object

After that, not mater how many times you adjust its angle, using Ctrl T will still produce a bounding box perpendicular to the object and not the document boundary.  Smart Objects have soooooo many uses.

When going back to a live shape, don't use Ctrl+T. Choose the rectangle tool and click on the shape layer again.

Ctrl+T gives you this :

Selecting the rectangle tool and the shape layer gives you this :

So you can then drag the side handles :
