Answer:
Step-by-step explanation:
Alright, lets get started.
The side length of square is given as 2.5.
So, the perimeter if square will be : [tex]4*2.5=10.0[/tex]
Once the side is doubled, means new dimension of side of square will be : [tex]2*2.5=5[/tex]
So the new perimeter will be : [tex]4*5=20[/tex]
The original perimeter is 10.
The new perimeter is 20.
It means the perimeter is twice the original perimeter. : Answer D
