You can put this solution on YOUR website! the perimeter of an isosceles triangle is 39cm. The longest side is 6cm longer than the shortest side. What are the lengths.
------------
s = longest side
s + 2(s-6) = 39
s = 17 cm
--> 17, 11, 11
=================
s = shortest side
s + 2(s+6) = 39
s = 9
--> 9, 15, 15
