How many isosceles triangles with whole-number length sides have a perimeter of 28 units?
+373 Hey there, Guest!
Okay, so first, let's list all the possibilities out:
1. (8, 8, 12)
2. (9, 9, 10)
3. (10, 10, 8)
4. (11, 11, 6)
5. (12, 12, 4)
6. (13, 13, 2)
So there you have it, there are 6 isosceles triangles.
Hope this helped! :)
