Answer:

Missing side: 6.5 cm

Perimeter: 15 cm

Step-by-step explanation:

The Pythagorean Theorem says that:

So, we can calculate the missing side of the triangle as:


c=\sqrt[]{6^2+2.5^2}

Then, solving for c, we get:


\begin{gathered} c=\sqrt[]{36+6.25} \\ c=\sqrt[]{42.25} \\ c=6.5 \end{gathered}

Therefore, the perimeter is the sum of the length of the side and it is equal to:

Perimeter = 6 cm + 2.5 cm + 6.5 cm

Perimeter = 15 cm

So, the missing side has 6.5 cm and the perimeter is 15 cm
