    Number of tiles used for covering the kitchen floor = 10

    Area covered by the floor = 6 * 5 feet^2

    = 30 square feet

    Length of each tiles = 3 feet

    Width of each tiles = w feet

    Area covered by each tiles = 3w square feet

    Then the equation can be written as

    3w * 10 = 30

    30w = 30

    w = 30/30

    = 1 feet

    So the width of each tiles is 1 feet. I hope the procedure is clear enough for you to understand. The equation to determine the solution is

    10 * 3w = 30

    There are 10 tiles used and the area covered by each tiles is 3w. Also the area of the floor is 30 square feet. All those information's have been used to get to the equation.
