Just a recommendation. Also, learn how to spell right. You look old enough to at least know how to spell.

Remember, triangles have 3 sides
OpenStudy (rainbow_rocks03):
oh yah
OpenStudy (rainbow_rocks03):
so the answer is 31?
OpenStudy (sleepyjess):
Yep, since isosceles triangles have 2 sides that are equal, and it says it has congruent sides of 9, that is 13 + 9 + 9
OpenStudy (rainbow_rocks03):
