For this case we have that the rug is rectangular.
By definition, the perimeter of a rectangle is given by:
![P = 2a + 2b = 2 (a + b)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/79gdi8v3bzxzyubqm3wj68813gita12lzc.png)
Where:
a, b: Represent the sides of the rectangle
Substituting according to the data we have:
![P = 2 (5 + 3)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/yr7atmctoeyoewo0fuoj4cinpp7v9uem3t.png)
Thus, the correct expression is option B.
