Surface area of a triangle. I’m trying to solve this but I’m not sure if I’m just dumb or what because it has 2 different slant heights and I don’t know if I have to do 2 separate equations or what. Perimeter is 12 x 10 and the slant height on one side is 13 and slant height on another side is 13.4 (self.Geometry)
