The GCF is what they all have in common.
2x is the only thing they ALL share.
The answer is 3 because flipped it’s the same but then cutting it in half is 3
The formula for solving perimeter of a parallelogram is P=2(a+b) where "a" is for the altitude and "b" for the base. From the give figure, we can determine both a and b values as enumerated below,
a=5
b=4
We can solve for P as shown below,
P=2(5+4)
P=18 unit.
Therefore, the perimeter is equal to 18.
I hope this helps, have a great day, and God bless.
