The perimeter of a triangle with sides of integer values is equal to 13. How many such triangles are possible? |
5 8 7 6 |
5 |
If the perimeter of the triangle is "p" let Total possible triangles "t" if p = even, then t = \(\frac{p^2}{48}\) if p = odd, then t = \(\frac{(p + 3)^2}{48}\) since, 13 is a odd number then, ∴ Total possible triangles = \(\frac{(13 + 3)^2}{48}\) = 5 |
