Calculation 43641

Hello, I can handle this task. Calculate the area and perimeter of an isosceles triangle if given: base a: 6cm, height to the base: 4cm.

Correct answer:

S =  12 cm²
o =  18 cm

Step-by-step explanation:

$$\begin{gathered} a=6\text{cn} \\ v=4\text{cn} \\ S=\frac{a\cdot v}{2}=\frac{6\cdot 4}{2}=12{\text{cm}}^2 \end{gathered}$$

$o=3\cdot a=3\cdot 6=18\text{cm}$
