To find the perimeter of a triangle, you add the lengths of all its sides together. For the right-angled triangle with sides of 3 cm, 4 cm, and 5 cm, the perimeter can be calculated as follows:
\[
\text{Perimeter} = 3 \, \text{cm} + 4 \, \text{cm} + 5 \, \text{cm}
\]
Calculating the sum:
\[
\text{Perimeter} = 3 + 4 + 5 = 12 \, \text{cm}
\]
So, the perimeter of the triangle is **12 cm**.
\[
\text{Perimeter} = 3 \, \text{cm} + 4 \, \text{cm} + 5 \, \text{cm}
\]
Calculating the sum:
\[
\text{Perimeter} = 3 + 4 + 5 = 12 \, \text{cm}
\]
So, the perimeter of the triangle is **12 cm**.
