let a = longest side       (Establishing labels)
let b = shortest side
let c = third side

P = 14.5                     (Given)
a = 6.2
b = 1/2(a)

P = a + b + c
P = 6.2 + 3.1 + c        (Fill in given info in equation)

P = 9.3 + c                (Simplify)

14.5 = 9.3 + c           (Simplify)

c = 14.5 - 9.3           (Solve)
c = 5.2

Hope this made sense!
