It is dilation by a factor of 5
Therefore the scale factor is 1 : 5
( you can figure this out bc 12 x 5 = 60 and 13 x 5 = 65, therefore the bigger shape is 5 times bigger)
You can also go 60 divided by 12 = 5 if you can’t tell that 12 x 5 = 60, is depends how comfortable you are with multiplication)
