It means that 673 of 9 inch tiles are required to cover an area of 400 square feet, when spacing the tiles a quarter inch apart.
Step-by-step explanation:
Given:
The function relating number of 9 inch tiles required and area to cover is:
![t(A)=\frac{144}{9.25^2}A](https://tex.z-dn.net/?f=t%28A%29%3D%5Cfrac%7B144%7D%7B9.25%5E2%7DA)
Now, plug in 400 for
to evaluate
.
![t(400)=\frac{144}{9.25^2}\times 400=\frac{144\times 400}{85.5625}=\frac{57600}{85.5625}=673.19\approx6225](https://tex.z-dn.net/?f=t%28400%29%3D%5Cfrac%7B144%7D%7B9.25%5E2%7D%5Ctimes%20400%3D%5Cfrac%7B144%5Ctimes%20400%7D%7B85.5625%7D%3D%5Cfrac%7B57600%7D%7B85.5625%7D%3D673.19%5Capprox6225)
Therefore, Don required 673 of 9 inch tiles to cover an area of 400 square feet, when spacing the tiles a quarter inch apart.
