Answer:
The length of the sides are 11.5 + 11.5 + 11 + 11.
Step-by-step explanation:
Because this is the perimeter of a quadrilateral, there have to be four numbers that you add together. Since you cannot divide 45 by four evenly, you have to look at the remainder of the quotient that you get from 45/4. The answer is 11 r1. Now you can take the remainder and split it in half to get 11.5. You have to use that number for two of the sides because this is a quadrilateral. When you add these two sides up, you get 23.0 or just 23. However, you need four sides, so you now take the other two 11s from the division and add those together to get 22. 22 + 23= 45.
