5 x 0.4 = 2 and

= 1.4142....... which is an irrational number
Solution is where the 2 lines intersect
I would say the answer is 3rd option, whre both lines pass through that point
If the scale factor is larger then 1, the new shape is larger
if the scale factor is smaller then 1, the new shape is smaller
so if the scale factor is 3....then the length of the new rectangle is 3 times larger then the original one
