hope it helps!

please mark as brainliest!!

thanks!!!

Step-by-step explanation:

the perimeter of a regular pentagon is 5 x each side

thus, we will multiply the length by 5.

920 x 5 = 4600

Answer 2

Given,

The length of the outside wall in feet$\[ = 920\]$

Solution,

Formula used, the perimeter of a pentagone$\[ = 5 \times {\rm{Side}}\,{\rm{length}}\]$

Therefore, the perimeter of the building

$\[\begin{array}{l} = 5 \times 420\\ = 2100\end{array}\]$

Hence, the perimeter of the building is $\[2100\]$feet.
