Question

the ratio of the sides of a triangle is 20:19:20. If the perimeter of the triangle is 354 inches, what are the lengths of all three sides.

Answer 1

120 in, 114 in, 120 in

Explanation:

The total of ratio units is 20+19+20 = 59, so each one stands for

(354 in)/(59) = 6 in

Then the side lengths are ...

20·(6 in) = 120 in

19·(6 in) = 114 in

and 120 in again.
