Answer:
The answer to your question is 90 cm, 150 cm, 210 cm
Step-by-step explanation:
Data
Proportion 3 : 5 : 7
Perimeter 450 cm
Process
1.- Sum the proportions to find the total number of parts.
3 + 5 + 7 = 15 parts
2.- Divide the perimeter by the total number of parts
450 / 15 = 30
3.- Find the measure of the sides multiplying each ratio by the previous result
Side 1 = 3(30) = 90 cm
Side 2 = 5(30) = 150 cm
Side 3 = 7(30) = 210 cm
