Question

The number of tiles needed for a bathroom floor is proportional to the area of the bathroom floor. Five tiles cover an area of 90 square inches. The bathroom floor has a total area of 3,024 square inches. Let n be equal to the total number of tiles needed for the floor. Set up and solve a proportion to find the value of n.( Show your work)

Answer 1

Given:

5 tiels cover the area 90square inch.

bathroom floor area is 3024

`\begin{gathered} 5\text{ tiles covers the area = 90} \\ 1\text{ tiles cover the area = }(90)/(5) \\ \text{ =18} \end{gathered}`

1 tiles cover the area is 18 square inch.

Let n tiles cover 3,024 square inch then:

`\begin{gathered} n*18=3024 \\ n=(3024)/(18) \\ n=168 \end{gathered}`

So 168 tiels required for cover the bathroom floor.
