a kitchen is shaped like a rectangle with dimensions of 11 1/2 ft. by 9 1/2 ft. the floor of the room is made of square tiles with a side length of 1.2 ft. What is the number of tiles that will cover the kitchen floor?

it's 437 because...

1. change(simplify) 11 1/2 and 9 1/2
23/2(11 1/2) and 19/2(9 1/2) because 11x2+1=23 and 9x2+1= 19
2. multiply straight across.
23/2 x 19/2 = 437(23 x 19)/4(2x2)
3. Divide it by the area of a square tile
area of square tile= 1/4 because... area= length x height and square tile mean a tile that has an equal size of length and height.
so 1/2x 1/2= 1/4
now divide 437/4 by 1/4, which is 437.
because... when you divide, you flip the fraction in the back and change the divide symbol to multiply, so it will look like 437/4 x 4/1(simplify to 4)=1748/4 = 437

so the answer is 437, but try to not cheat while the test and use my answer on test CORRECTIONS

If you want to know the number of whole tiles, then

11.5/1.2 = 9.6
9.5/1.2 = 7.9

So, assuming the cut pieces are not used, you will need

10x8 = 80 tiles

437 tiles

how did you get 437

Sorry about that.

To find the number of tiles that will cover the kitchen floor, we need to calculate the area of the floor and divide it by the area of each tile.

Step 1: Find the area of the floor.
The area of a rectangle is calculated by multiplying its length by its width.
Area of the kitchen floor = Length x Width
= 11.5 ft x 9.5 ft

Step 2: Convert the dimensions into the same units as the tiles.
Since the tiles are measured in feet, it's important to have the same units for accurate calculation.

Step 3: Calculate the area of a single tile.
The area of a square is calculated by multiplying its side length by itself.
Area of a tile = Side length x Side length
= 1.2 ft x 1.2 ft

Step 4: Divide the area of the floor by the area of a single tile.
Number of tiles needed = Area of the floor / Area of a single tile

Now let's calculate it using the given dimensions:

Step 1: Area of the floor = 11.5 ft x 9.5 ft = 109.25 ft²
Step 2: The units are already in feet, so no conversion is needed.
Step 3: Area of a tile = 1.2 ft x 1.2 ft = 1.44 ft²
Step 4: Number of tiles needed = 109.25 ft² / 1.44 ft²

Calculating the division:

Number of tiles needed ≈ 75.8681

Since you can't have a fraction of a tile, you should always round up to the nearest whole number when calculating the number of tiles needed. Therefore, you would need 76 tiles to cover the kitchen floor.
