This is a Triangle. The perimeter of a triangle is given by the sum of all sides:
[tex]\begin{gathered} P=a+b+c \\ a,b,c=\text{the sides of the triangle} \\ a=5,b=5,c=6 \\ P=5+5+6=16 \\ P=16units \end{gathered}[/tex]
Area of triangle is given by 1/2 * bh
[tex]\begin{gathered} A=\frac{1}{2}bh+\frac{1}{2}bh(For2\text{Triangles)} \\ \Rightarrow A=bh \\ b=6,h=4 \\ A=6\cdot4=24 \\ A=24units^2 \end{gathered}[/tex]
