Dimensions

[Guest]

A straight passageway is constructed of tiles 7 inches square (7 inches in length and 7 inches in width). The assumption is 9 1/2 tiles in a row from wall to wall and 156 tiles in a row from end to end. If no measuring device is available, how would the dimensions be determined ?
