Question

Bailey wants to add a room onto her patio using a ratio of 9 to 4 for its dimensions. If theaddition will be 10 feet wide, how long will the room be to the nearest tenth?

Answer 1

We know that the ratio is 9 to 4.

Now, to find the answer, we have to use the following proportion

`(9)/(4)=(l)/(10)`

Then, we solve for the length

`\begin{gathered} l=(9\cdot10)/(4) \\ l=22.5 \end{gathered}`

Hence, the length is 22.5 feet.
