Question

Which pairs of rectangles are similar polygons?

pls help me

Answer 1

3.√

4.√

Explanation:

similar rectangles have proportional sides so compare corresponding sides to check

1. 169/1.3 = 49/0.7 → 130 ≠70 no

2. 18.55/5.3 = 10.5/3.5 → 3.5 ≠ 3 no

3. 120/24 = 60/12 → 5 = 5 yes

4. 189/2.1 = 81/0.9 → 90 = 90 yes
