Answer 1

Explicación paso a paso:

Teorema de pitagoras

${a}^{2} + {b}^{2} = {c}^{2} \\ {2}^{2} + {b}^{2} = ( \sqrt{13} ) {}^{2} \\ 4 + {b}^{2} = 13 \\ {b}^{2} = 13 - 4 \\ {b}^{2} = 9 \\ b = \sqrt{9} \\ b =3$

Área del triángulo

$a = \frac{b \times h}{2} = \frac{5 \times 2}{2} \\ \\ \frac{10}{2} = 5cm {}^{2}$
