Question

The ratio of the measures of the sides of a triangle is 3:5:7, And it's perimeter is 450 cm. Find the measures of each side of the traiand it's perimeter is 450 cm. Find the measures of each side of the triangle

Answer 1

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
