Noah needs 126 tiles to cover his kitchen floor, which measures 18 feet by 7 feet since each tile covers 1 square foot.
To ascertain the number of tiles required for Noah's kitchen floor, a straightforward approach involves calculating the floor area and subsequently determining how many individual tiles are needed. Given that each tile covers precisely 1 square foot, the total number of tiles equals the area of the floor. By multiplying the length and width of the kitchen floor—measuring 18 feet by 7 feet—the resulting area is determined to be 126 square feet.
The application of the formula: Area = Length × Width, where the length is 18 feet and the width is 7 feet, yields the total floor area. Since each tile covers 1 square foot, the total number of tiles needed corresponds to the calculated area. Therefore, Noah will require a total of 126 tiles to effectively cover his kitchen floor, providing a practical and quantitative solution for his tiling project. This systematic approach ensures accuracy and efficiency in determining the necessary quantity of tiles for the given dimensions of the kitchen floor.
