The length 4

The length of a rectangular room measures twice a number x increased by 5. The width measures a number x increased by 3. What is the perimeter of the room?

Result

p = (Correct answer is: 4x+16)

Step-by-step explanation:

$$\begin{gathered} a=x+5=5 \\ b=x+3=3 \\ p=2(a+b) \\ p=2((x+5)+(x+3)) \\ p=2(x+5+x+3) \\ p=2(2x+8) \\ p=4x+16 \end{gathered}$$
