PLEASE HELP IM I HAVE A TEST RIGHT NOW Demarco tiles a bathroom floor. He has a scale drawing in which the side lengths of each unit square represents 2 ft. Demarco uses square tiles that are 1/2 ft wide. How many tiles does Demarco need? and i gotta show my work

Respuesta :

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 rule of three is given by:

1 tile - 0.5 ft

x tiles - 2 ft

Applying cross multiplication:

[tex]0.5x = 2[/tex]

[tex]x = \frac{2}{0.5}[/tex]

[tex]x = 4[/tex]

Thus, Demarco needs 4 tiles.
