For a triangle, sum of any two sides of triangle must be greater than the third side of triangle.
Check for the sides of triangle.
[tex]\begin{gathered} 8+4>3 \\ 11>3 \end{gathered}[/tex][tex]\begin{gathered} 4+3>8 \\ 7\text{ is not greater than 8 } \end{gathered}[/tex]So there is no triangle with such dimensions as sum of side 3 and 4 is not greater than 8.
Answer: No triangle
