We are asked to determine whether the given two polygons are similar or not.
Recall that the two polygons are said to be similar if the ratio of their corresponding sides is equal.
The corresponding sides of the two polygons are
side 3 = side 6
side 4 = side 8
side 5.5 = side 11
Let us check if they are in the same ratio
As you can see, the ratio of the corresponding sides is equal.
Therefore, the given pair of polygons is similar.
