Please let me know if you want me to add an explanation as to why this is the answer. I can definitely do that, I just wouldn’t want to write it if you don’t want me to :)

36 in, 28 in, 20 in

Step-by-step explanation:

sum the parts of the ratio, 9 + 7 + 5 = 21 parts

Divide the perimeter by 21 to find the value of one part of the ratio

84 in ÷ 21 = 4 in ← value of 1 part of the ratio, then

9 parts = 9 × 4 in = 36 in

7 parts = 7 × 4 in = 28 in

5 parts = 5 × 4 in = 20 in

The measure of the sides are 36 in, 28 in and 20 in
