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 side length of 1/2 ft. What is the number of tiles that will cover the kitchen floor?

11 1/2= 23 halves 9 1/2= 19 havles multiply those by each other and that's your answer

The area of the floor is  11.5 x 9.5  =  109.25 square feet.

The area of each tile is:  0.5 x 0.5  =  0.25 square feet.

Dividing  109.25  by  0.25  gives an answer of  437  tiles.

Here's a third explanation lol laugh

 

How many pairs of apples are there in a batch of 10 apples? 10 ÷ 2 = 5 pairs of apples

 

How many \(\frac12\times\frac12=\frac14\) square feet tiles are there in \( 11\frac12\times9\frac12 = \frac{437}{4} \) square feet?

 

\(\frac{437}{4} \div \frac14 =\frac{437}{4}\times\frac41=437\) one-fourth square feet, or tiles
