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:
Thus, Demarco needs 4 tiles.

Answer: 24.5
Step-by-step explanation:
So you have to remember that some sections are broken into medians so you have a 2:1 ratio in some areas. So XZ is 15 right, so you'd have to divide that section by 2 to get 7.5 for XY and FZ. Next FY is split into a 2 to 1 ratio with the YC being the larger one part to that would be the 2 and the FC being the smaller part to it's 1, so you'd divide the 21 using the 2:1 so FC would be 7 and YC would be 14. Lastly, there's XE. So XE would be split into a 2:1 ratio having the XC being the bigger part so it would be 2 and CE being the smaller part to it would be 1. So XC is 10 and CE is 5.
So now add together 7.5+7+10 to get the answer 24.5
