A right‑angled triangle has legs of length $6\text{ cm}$ and $8\text{ cm}$. Find its perimeter.

Step-by-step solution

1. Determine the hypotenuse using Pythagoras: $c=\sqrt{6^2+8^2}$.
2. Compute the hypotenuse: $c=\sqrt{36+64}=10$ cm.
3. Add the three sides: $6+8+10=24$ cm.
4. Thus, the perimeter is $24$ cm.
