Kalkulator

$$ \begin{aligned} L &= \pi r^2 \\ \\ K &= 2 \cdot \pi r \end{aligned} $$

$$ \begin{aligned} L &= \frac{a t_a}{2} \\ \\ K &= a + b + c \end{aligned} $$

segitiga siku-siku

$$ \begin{aligned} L &= \frac{ab}{2} \\ \\ K &= a + b + c \end{aligned} $$

$$ \begin{aligned} L &= a \cdot a = a^2 \\ \\ K &= 4 \cdot a \end{aligned} $$

persegi panjang

$$ \begin{aligned} L &= ab \\ \\ K &= 2 \cdot (a + b) \end{aligned} $$

$$ \begin{aligned} L &= a t \\ \\ K &= 4 \cdot a \end{aligned} $$
