Answer by richwmiller(17219) (Show Source): You can put this solution on YOUR website!
There are an infinite number of triangles with perimeter 78cm.
There are fewer isosceles triangles with perimeter 78 cm and one side 28.
If another side is also 28 the the third side is 78-56=22
if another side is not 28 then we have 78-28=50
The other sides are 25 each.
