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

20*6 - 120

20*6 = 120

19 * 6 = 114

Explanation:

Call x the scale factor.

20x + 19x + 20x = 354 Add the left side together.

59x = 354 Divide by 59

59x/59 = 354/59 Combine and cancel

x = 6

The lengths of the sides are

20 * 6 = 120

19 * 6 = 114

20 * 6 = 120

Total 354 Check
