:
Write an equation for each statement:
:
its perimeter is 5,500 kilometers, 
a + b + c = 5500
;
the shortest side measures 134 kilometers less than the second side,
c = b - 134
:
 the longest side measures 670 kilometers more than the second side.
a = b + 670
:
find the lengths of the three sides 
replace a and c using the above information
(b+670) + b + (b-134) = 5500
3b + 670 - 134 = 5500
3b + 536 = 5500
3b = 5500 - 536
3b = 4964
b = {{{4964/3}}}
b = 1654{{{2/3}}} km is the 2nd side
find the 1st side
a = 1654{{{2/3}}} + 670
a = 2324{{{2/3}}} km is the 1st side
and
c = 1654{{{2/3}}} - 134
c = 1520{{{2/3}}} km is the 3rd side
;
:
You can check this by adding up these three sides and ensure that the sum is 5500
