Answer:
A, F
Step-by-step explanation:
The perimeter of a polygon is equal to the sum of all side lengths.
We have the side lengths
[tex]s,\ s+\frac{1}{2},\ s,\ s+\frac{1}{2}[/tex]
The perimeter:
[tex]s+s+s+\frac{1}{2}+s+\frac{1}{2}=(s+s+s+s)+\left(\frac{1}{2}+\frac{1}{2}\right)=4s+1\\\\4s+1=(2)(2s)(2)\left(\frac{1}{2}\right)=2\left(2s+\frac{1}{2}\right)[/tex]
