Electronic – How to change the dimensions of a PCB in Altium Designer 19.1 using by entering the value I want the dimension to be

How do I change the dimensions of a PCB in Altium Designer 19.1 using by entering the value I want the dimension to be?

Please for the love of 555 DO NOT tell me how to edit the size using the mouse OR by editing the grid snap size. I want to actually define the width and length of a rectangular PCB.

EDIT: Clarification: What I meant when I said do not tell me how to edit using the mouse is that I didn't want someone to tell me I can click and drag the board edges to resize (as this is a very inaccurate way set dimensions). A good example of what I want to do can be taken from SolidWorks, in Solidworks when you can type in the value (mm, inches, etc) of the line you've just clicked on to define its length. That's what I want to do except for the width and length of a PCB.

Create a polygon (place polygon plane) on whatever layer you like. Mechanical 1 is a good choice since it is often used by Gerber export as the board outline layer. The "Outline Vertices" shown in the object properties when it is selected will allow you to specify exact values. When done, select Design > Board Shape > Define from Selected Objects.
