Question

if you need to install carpet in a room that is 80ft x 50ft how many 10ft x 50ft rolls of carpet do you need to cover the room

Answer 1

Given:

The dimensions of the room are,

`\begin{gathered} l=80ft \\ b=50ft \end{gathered}`

The dimensions of the carpet are,

`\begin{gathered} l_1=10ft \\ b_1=50ft \end{gathered}`

To find:

The number of rolls of carpet.

Step-by-step explanation:

The number of rolls of carpet is calculated by,

`\begin{gathered} \frac{Area\text{ of the room}}{Area\text{ of a carpet rool}}=(l* b)/(l_1* b_1) \\ =(80*50)/(10*50) \\ =8rolls\text{ of carpet} \end{gathered}`

Therefore, the number of rolls of carpet is 8.

Final answer:

The number of rolls of carpet is 8.
