A bathroom floor has dimensions of 15 feet long by 6 feet wide if andrew covers the floor with the square tiles measuring 18 inches or 1.5 feet on one side how many square tiles does he need

To determine how many square tiles Andrew needs to cover the bathroom floor, follow these steps:

### Step 1: Calculate the Area of the Bathroom Floor
The dimensions of the bathroom floor are 15 feet long by 6 feet wide. The area of the floor is calculated as:
\[
\text{Area of the floor} = \text{Length} \times \text{Width} = 15 \text{ feet} \times 6 \text{ feet} = 90 \text{ square feet}
\]

### Step 2: Calculate the Area of One Square Tile
Each square tile measures 1.5 feet on each side. The area of one tile is:
\[
\text{Area of one tile} = 1.5 \text{ feet} \times 1.5 \text{ feet} = 2.25 \text{ square feet}
\]

### Step 3: Determine the Number of Tiles Needed
To find the total number of tiles required, divide the area of the floor by the area of one tile:
\[
\text{Number of tiles} = \frac{\text{Area of the floor}}{\text{Area of one tile}} = \frac{90 \text{ square feet}}{2.25 \text{ square feet per tile}} = 40 \text{ tiles}
\]

So, Andrew needs **40 square tiles** to cover the bathroom floor.
