What is the perimeter of a figure?

The perimeter of a figure is given by the total length of it's boundary.

In this problem, we have that:

  • The bottom boundary has length of 10 units.
  • The two lateral boundaries have lengths of 7 units.
  • There are two top boundaries, which are the hypotenuses of a right triangle with legs 3 and 5, hence:

[tex]t = \sqrt{3^2 + 5^2} = 5.83[/tex]

Hence the perimeter of the figure is:

P = 10 + 2 x 7 + 2 x 5.83 = 35.66.

Rounding, it is of about 36 ft, hence option A is correct.
