It looks like the sides are based on the longest side.  So we will call the longest side s.  "One side of a triangle is half the longest side" so this side is .5s (cuz s is the longest side, so this side is one-half of that), and the third side is "12 meters less than the longest side" so this side is s-12.  Now we have all three sides in terms of our longest side s.  The perimeter is found by adding all three of them together.  If the perimeter is 58, then:|dw:1412637809795:dw|
