Question

The ratio of the measures of the three sides of a triangle is 9: 7: 5 . Its perimeter is 191.1 inches. Find the measure of each side.

Answer 1

81.9 inches, 63.7 inches, 45.5 inches respectively

Explanation:

Total number of units = 9+7+5 = 21

21 units = 191.1 inches

1 unit = 191.1/21 = 9.1 inches

9 units = 9.1 x 9 = 81.9 inches

7 units = 9.1 x 7 = 63.7 inches

5 units = 9.1 x 5 = 45.5 inches
