Answer:
rectangles 1 and 2 are similar
Step-by-step explanation:
Geometric figures are similar if corresponding sides are proportional.

We can form the ratios of (long side)/(short side) to see which rectangles are similar:
1: long side = 6, short side = 4. (long side)/(short side) = 6/4 = 3/2
2: long side = 9, short side = 6. (long side)/(short side) = 9/6 = 3/2
3: long side = 8, short side = 5. (long side)/(short side) = 8/5
Only rectangles 1 and 2 have corresponding sides in the same ratio.
Rectangles 1 and 2 are similar.
