you must cover the entire bathroom floor with tiles. each tile measures 1 ft. x 1 ft. You will need an extra 5% of tiles to account for waste. How many tiles will you need to purchase for the project?

The floor measures 5ft. x 7ft.

5 * 7 * 1.05 = ?

Round up to the nearest whole tile.

36.1

To find out how many tiles you will need to purchase for the project, you first need to calculate the total area of the bathroom floor.

The floor measures 5 ft. x 7 ft., so the total area is:

5 ft. x 7 ft. = 35 square ft.

Now, you need to account for waste by adding an extra 5% of tiles. To do this, you need to calculate 5% of the total area.

5% of 35 square ft. = (5/100) x 35 square ft. = 1.75 square ft.

Next, you need to determine the area of a single tile. Each tile measures 1 ft. x 1 ft., so the area is:

1 ft. x 1 ft. = 1 square ft.

To find out how many tiles you will need, divide the total area (including waste) by the area of a single tile.

Total area including waste = 35 square ft. + 1.75 square ft. = 36.75 square ft.

Number of tiles needed = Total area including waste / Area of a single tile

Number of tiles needed = 36.75 square ft. / 1 square ft.

Number of tiles needed = 36.75 tiles

Since you can't purchase partial tiles, you will need to round up to the nearest whole number. Therefore, you will need to purchase 37 tiles for the project.
