    Question

    The floor of a hall measuring 16 meters in length and 12 meters in width is to be paved with square tiles. If the least number of tiles are to be used, then what is the length of each square tile?

    A.

    12 meters

    B.

    24 meters

    C.

    48 meters

    D.

    4 meters

    Correct option is D

    Given:

    length of hall = 16m

    breadth of hall =14m

    Solution:

    length of largest side of square tile which can place in the hall is HCF of  length and breadth of hall.

    side of square tile = HCF if 16m and 12m

                                = 4m

    So, side of the square tile = 4m.
