First, we need to calculate the length of the arc at the bottom right corner.

This arc is a quarter of a complete circle. The perimeter of a complete circle is computed as follows:

[tex]P=2\cdot\pi\cdot r[/tex]

Then, the length of the arc is (the radius is 5):

[tex]\begin{gathered} P=2\cdot3.14\cdot5\cdot\frac{1}{4} \\ P=7.85 \end{gathered}[/tex]

Therefore, the perimeter of the figure is:

5 + 10 + 10 + 5 + 7.85 = 37.85 ≈ 38
