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

65; 117; 143.

Step-by-step 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.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
