Answer:

20*6 - 120

20*6 = 120

19 * 6 = 114

Step-by-step 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
