Given data:

RSTV is a square.

Side, RS = 12cm

If square is dilated by a scale factor of 3 about a given centre then,


RS=12*3
RS\text{ = 36cm}

Now, perimeter of square is


P\text{ = RS }*4
\begin{gathered} P\text{ = 36}*4 \\ \text{ =144cm} \end{gathered}

Thus, the correct option is (3) that is 144cm
