Here is your answer

[tex]\bold{107.62} inches [/tex]

Since the door will be in shape of a rectangle where,

length= 80 inches

breadth= 72 inches

So,

widht of largest mattress that can fit diagonally is diagonal of the door.

i.e.

[tex]d= \sqrt{{l}^{2}+{b}^{2}}[/tex]

[tex]d= \sqrt{{80}^{2}+{72}^{2}}[/tex]

[tex]d= \sqrt{6400+5184}[/tex]

[tex]d= \sqrt{11584}[/tex]

[tex]d= 107.62[/tex]
