2- This room is 3 meters wide = the width of this room is 3 meters. /ærz e in ota:gh seh metr æst/.

3- This wall is 2 meters high = the height of this wall is 2 meters. /ertefa: e in diva:r do metr æst/.
Ertefa e in divar
4- This water is 1 meter deep = the depth of this water is 1 meter. /omgh e in a:b yek metr æst/.

If you are talking about shapes, you could simply add the word /beh shekl e/ like below.
6- This table is square. /in mi:z beh shekl e moræb.bæ æst/.

9- The backgammon dices are cubical. /ta:s e tækhteh nærd beh shekl e mokæ.æb æst/.

In such sentences (6-9), you could simply delete /beh shekl e/ and add to the end of each shape.
