Can y’all help me with the question in the picture please? I don’t understand it and I’ve been stuck on it for a while

Answer 1

The scale factor is 2.

Explanation:

Take the vertical sides of the 2 triangles.

Their length is 3 and 6 so the scale factor is 6/3 = 2.

Also we see than the horizontal lines are in the same ratio 4 : 2 = 2:1.
