Answer 1

40 : 60 : 90

Explanation:

To solve this add the total of all the numbers of the ratio. 4 + 6 + 9 = 19.

Take that total and divide the perimeter by it: 190 / 19 = 10.

So each of those ratios need to be multiplied by 10.

Final answers: 40 : 60 : 90. They have a ratio of 4:6:9 and add up to 190.
