Question

3. The aspect ratio of a rectangular shape is its length divided by its width (L/W). If theaspect ratio of a chalkboard is 4.3 and the width is 5 in, what is the length of thechalkboard?

Answer 1

The lenght is 6.667 in.

Step-by-step explanation:

Given:

`\begin{gathered} (L)/(W)=(4)/(3) \\ \text{And:} \\ W=5 \end{gathered}`

Then:

`\begin{gathered} (L)/(5)=(4)/(3) \\ L=(4\cdot5)/(3) \\ L=(20)/(3) \\ L=6.67\text{ in} \end{gathered}`

So, the length is 6.67 in.
