Consider that the perimeter of any geometrical figure is the sum of the lengths of all external boundaries of the figure.

1.

The given diagram is a triangle with sides measuring 3 cm, 3 cm, and 5 cm.

So the perimeter (P) of this triangle will be the sum of its three sides,

[tex]\begin{gathered} P=3\text{ cm}+3\text{ cm}+5\text{ cm} \\ P=11\text{ cm} \end{gathered}[/tex]

Thus, the perimeter of the given figure is 11 centimeters.
