Answer:

Step-by-step explanation:
Longest side of ∆ = 2a = 6.2 cm
If the shortest side is, a, and we are told that the longest side is twice the shortest side, therefore, length of shortest side is
The sum of the 3 sides = perimeter = 14.5 cm
Thus,

Plug in the values of a and b

The equation that can be used to find the side lengths is 
When put in a calculator, the answer is 12.22 (recurring)
