let the shortest side be , the longest side , and the third side
if the shortest side is meters less than the longest side we have
....eq.1

if the length of the third side is meters less than the length of the longest side, we have
....eq.2

If the perimeter is meters, we have
....eq.3

substitute and
....eq.3, solve for

go to
....eq.1, substitute

go to
