In rectangle A, the length and breadth of rectangle A is
[tex]\begin{gathered} L=6 \\ B=4 \end{gathered}[/tex]
In rectangle B, the length and breadth of rectangle B is
[tex]\begin{gathered} L=30 \\ B=20 \end{gathered}[/tex]
So, the length and breadth of rectangle B is 5 times the length and breadth of rectangle A.
Hence, the scale factor will be 5.
