Answer:
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
