Using the center and a scale factor of 3/2, we can say that the length A'B' will be


A^(\prime)B^(\prime)=f\cdot AB

Where f is the scale factor, then


\begin{gathered} A^(\prime)B^(\prime)=(3)/(2)\cdot4 \\ \\ A^(\prime)B^(\prime)=3\cdot2 \\ \\ A^(\prime)B^(\prime)=6 \end{gathered}

The length of A'B' is 6 units.

One of the properties of dilations is that the angles are always the same. Therefore the angle B' is the same angle as B.
