Let

x---------> measure of the base of the triangle of the image

y---------> measure of the base of the triangle of the pre-image

sf-------> the scale factor

we know that

the scale factor is equal to

sf=(x)/(y)

in this problem we have

$x=6\ units\\y=3\ units$

Find the scale factor

substitute the values of x and y in the formula above

sf=(6)/(3)=2

therefore

the answer is

the scale factor is equal to
