Find the perimeter of the figure below, in meters.9.2 m5.9 m5.9 m5.9 m5.9 m3.9 m3.9 m5.9 m5.9 m13 m13 m9.2 mNOT to scale)

Answer 1

To find the perimeter (P) we need to add all the lengths of the figure, as follows:

$\begin{gathered} P=9.2+5.9+5.9+3.9+5.9+13+9.2+13+5.9+3.9+5.9+5.9 \\ P=2\cdot9.2+6\cdot5.9+2\cdot3.9+2\cdot13 \\ P=18.4+35.4+7.8+26 \\ P=87.6\text{ m} \end{gathered}$
