    Since one foot on the bottom will not be covered we need to cover a wall that is 8 feet tall by 22 feet long.

    A = bh or area = 8 x 22 = 176 square feet.

    Each tile is 2 x 2 or 4 ft ²

    So the question becomes, "How many 4ft² tiles do we need to cover 176 ft²"?

    176 : 4 = 44 tiles

    Size of each tiles = (2*2) square inch

    = 4 square inch

    Since 1 inch gap needs to be kept with the floor, so the height of floor that needs to be covered with square mirror tiles is 8 inch.

    Size of each wall = (8*22) square inch

    = 176 square inch

    So the number of mirror tiles required per wall = 176/4 tiles

    = 44 tiles

    Number of tiles required to cover both walls = (44*2) tiles

    = 88 tiles.
