Answer: B. 12
Step-by-step explanation:
We know that a parallelogram is a quadrilateral having opposite sides congruent to each other .
In the given picture , we have a parallelogram TUVW in which [tex]\overline{VW}=12\text{ units}[/tex] and [tex]\overline{UV}=7\text{ units}[/tex]
Then by the properties of parallelogram , we have
[tex]\overline{TU}\cong\overline{VW}\\\\\overline{UV}\cong\overline{TW}[/tex]
Then , [tex]\overline{TU}=12\text{ units}\ \ \cong\overline{TW}=\text{ 7units}[/tex]
