Question

The ratio of three sides of a triangle are 5:9:11. There perimeter of the triangle is 325. Find the

measure of each side of the triangle

Answer 1

65; 117; 143.

Explanation:

1. if the ratio is 5/9/11 and the perimeter is a+b+c=325, then it is possible to write (for the perimeter):

5x+9x+11x=325;

2. to calculate the value of 'x':

x=13;

3. the required sides are:

5x=65; 9x=117; 11x=143.
