    5m

    Explanation:

    The longest metallic rod can be placed diagonally on the floor

    Thus we need to find the length of the diagonal of the room

    Formula for diagonal = root of (length squared + breadth squared)

    =V16 + 9

    =V25

    =5m

    Therefore the longest rod is of 5m
