Answer:

The perimeter is around 27 centimeters.

Step-by-step explanation:

Givens

  • Each leg is 8 centimeters long.
  • The angles of the right triangle are 45°, 45° and 90
  • °.

Remember that the perimeter is the sum of all sides. So, we just need to find the hypothenuse using Pitagorean's Theorem.

[tex]h^{2}=8^{2} +8^{2}\\ h=\sqrt{64+64}=\sqrt{128} \approx 11[/tex]

The perimeter would be

[tex]P=8+8+11\\P=27[/tex]

Therefore, the perimeter is around 27 centimeters.
