Answer 1

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)
