Q. Angela is building a pool that is

\mathbf{2 5}

meters long. She has selected tiles to put around the edge of the pool. If each tile is

8

inches long, how many tiles does she need for one

25

-meter side of the pool?

\newline

(

1

meter

\approx 3.28

feet)

Convert to Inches: First, we need to convert the length of the pool from meters to inches, because the tile length is given in inches. There are $3.28$ feet in a meter, and $12$ inches in a foot. So, we will multiply the length of the pool by $3.28$ to convert it to feet, and then by $12$ to convert it to inches. $\newline$ Calculation: $25 \text{ meters} \times 3.28 \text{ feet/meter} \times 12 \text{ inches/foot}$
Total Length Calculation: Now, let's perform the multiplication to find the total length in inches. $\newline$ Calculation: $25 \times 3.28 \times 12 = 82$ feet $\times 12 = 984$ inches
Tiles Needed Calculation: Next, we need to divide the total length of the pool side in inches by the length of one tile to find out how many tiles are needed. $\newline$ Calculation: $984 \, \text{inches} / 8 \, \text{inches/tile}$
Number of Tiles: Performing the division gives us the number of tiles needed. $\newline$ Calculation: $984 / 8 = 123$ tiles
