Answer:
A) LEngth of FG is 2 units
Explanation:
Considering the diagram attached below.
Reflection of any polygon does not affects its length.
As it is given both polygons are reflection of each other so their sides are congruent.
AB ≅ EF = 3 units
BC ≅ FG = 2 units
CD ≅ GH = 2.2 units
DA ≅ HE = 3.2 units
