MA AJUTATI VA ROOOGG??​

Answer 1

Răspuns:

Explicație pas cu pas:

AC imparte paralelogramul in 2 triunghiuri egale.

A ΔABC = (AB*AC*sin 45°)/2

A paralelogram = 2*A ΔABC = 2*(AB*AC*sin 45°)/2 = AB*AC*sin 45°

A paralelogram = 4*6*√2/2 = 12√2

Answer 2

$\it \mathcal{A}_{ABCD}=2\cdot \mathcal{A}_{ABC}=2\cdot\dfrac{AB\cdot AC\cdot sin45^o}{2}=4\cdot6\cdot\dfrac{\sqrt2}{2}=12\sqrt2$
