I have no idea how to solve this one, but the link is at the top of the picture if you can see it lol please help asap!! I will try and give whoever solves it first brainliest!

the scale factor can be 10 because 10 times 3 =30

Step-by-step explanation:

I watch that 2 weeks ago but never giving just one number

9 + 3 + 6 + 3 + 3 +6 = 30

Step-by-step explanation:

    So, first of all you need to find the perimeter of the figure. The perimeter is the length of all sides added together. This polygon has 6 sides, and so we have to add 6 numbers together. The first side is 3 units, the second side is 1 unit, the third side is 2 units, the forth side is 1 unit, the fifth side is 1 unit, and the sixth side is 2 units. 3+1+2+1+1+2. That equals 10. The starting perimeter is ten. So, to make the polygon have a perimeter of 30 units you will need to expand the polygon. This means that you multiply the width and height by a number to make the polygon a specific number of times larger. We want the perimeter to go from 10 units to 30 units, which would be an expansion of a factor of 3. 10 times 3 equals thirty, right. So in total the entire polygon would be multiplied by 3. So each of your side lengths will be multiplied by 3. the first one is 3, so 3 times three is 9. the second one is 1, so 1 times 3 is 3. etc. Your new, expanded polygon will have a perimeter of 30 units. 9+3+6+3+3+6=30. :) your welcome
