Solution
Given a triangle of the followingdimensions
[tex]19in,17in,14in[/tex]
To find the perimeter, P, of a triangle, the formula is
[tex]\begin{gathered} P=a+b+c \\ \text{Where a, b and c are the side lengths} \end{gathered}[/tex]
Then,
[tex]\begin{gathered} a=19in \\ b=17in \\ c=14in \end{gathered}[/tex]
Substitute the values to find P.
[tex]\begin{gathered} P=a+b+c \\ P=19+17+14=50in_{} \\ P=50in \end{gathered}[/tex]
Hence, the perimeter, P, is 50 inches
