For this problem you could use the Pythagorean theorem.
The Pythagorean theorem states that for any right triangle
Where A and B are the sides of the triangle and C is the hypotenuse.
----------------------
Use the theorem to solve for C
A = 8
B = 8

Take the squar root of both sides

*Note that value is rounded.
-------------------------
Now add all of the sides together to find the perimeter.

The perimeter is 21.31cm
