Answer:
Step-by-step explanation:
If the longest side is 6.2 cm, and it is twice the length of the shortest, then we can write an equation as 2x=6.2, where x is the short side length.
Then, since a triangle has 3 sides, the medium side length is 14.5-6.2-x.

x=5
x^2+6=31 Find x
Subtract 6 from both sides
x^2=25
take the square root of both sides
x=+5 or -5
