(How would you show your prayer life to others who are not member/s of you sect or religion?) 3 or more paragraph.

If I understand correctly, the question is saying that the rectangles have the same proportions and wants to know the right side length of the smaller rectangle.
If this is the case, then the proportion is 5:3, with 3 being the right side length of the smaller rectangle.
This is because The original is 10:6, which is equal to 5:3.
Also, 5 is half of 10, so to find the right side length, just half the original as well, since you have to do the same to both sides. This results in lengths of 5 and 3.

Hope this helps :)
