Using proportions, it is found that Demarco needs 4 tiles.
----------------------
- This question is solved by proportions, using a rule of three.
- Each tile uses 1/2 = 0.5 ft.
- In total, he needs 2 ft.
Thus, the<u> rule of three</u> is given by:
1 tile - 0.5 ft
x tiles - 2 ft
Applying cross multiplication:
![0.5x = 2](https://tex.z-dn.net/?f=0.5x%20%3D%202)
![x = \frac{2}{0.5}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B2%7D%7B0.5%7D)
![x = 4](https://tex.z-dn.net/?f=x%20%3D%204)
Thus, Demarco needs 4 tiles.
