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

The measures of each side of the triangle are 90cm, 150cm and 210cm

If the measures of the sides of a triangle is 3:5:7 and its perimeter is 450 cm, then the ratio of the sides will be:

3x:5x:7x

Taking the sum of the ratios and sum it to 450cm, wee will have;

3x + 5x + 7x  = 450

15x = 450

x = 450/15

x = 30

The first side = 3x = 3(30) = 90cm

Second sidee  = 5(30) = 150cm

Thirs side  = 7(30) = 210cm

Hence the measures of each side of the triangle are 90cm, 150cm and 210cm

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
