The dimensions (measurements) of a hall ...

The dimensions (measurements) of a hall are 12m, 4 m and 3, respectively. An ant starts at one corner of the hall, travels only along the adgees and reaches a diagonally opposite, corner, taking the shortest possible route. Find the distance travelled by the at t and its magnitude of displacement .
