Simple question about typing dimensions

I am having trouble typing in dimension when i am dragging a rectangle
I know it is a simple question
But looking for help

what’s the problem exactly?

Start the rectangle by clicking and releasing the mouse button. Drag inthe mouse in the desired direction. Let go of the mouse and start typing the dimensions. then hit enter. Usually the form would be like 4,7 but if you use a comma for a decimal separator. use a semicolon as the dimension separator as in 4;7.

what if it will not let you type the dimensions? It does not display dimensions it says measurements, how do I switch it to dimensions?

The label for the Measurements box changes depending upon the tool you are using.

Try doing what i said. Exactly as I wrote it.

I think the problem is that the wrong tool was selected. I will try again
Thanks
