AM NEVOIE URGENT DE REZOLVARE !!!!! VA ROG !!!!

Answer 1

Răspuns:

Explicație pas cu pas:

A -aria

A(BCDPGHEB) = A(APGF) - {A(ABCD) + A(GHEF)}

A(APGF) = AP·GP = 3·2 m² = 6 m²

A(ABCD) = AB² = 1 m²

A(GHEF) = (EH + FG)·EF/2 = (1+2)·1/2 m² = 3/2 m² = 1,5 m²

⇒ A(BCDPGHEB) = 6-(1+1,5) m² = 3,5 m²

Answer 2

$\it \mathcal{A}_{AFGP}=2\cdot3=6m^2\\ \\ \mathcal{A}_{ABCD}=1^2=1m^2\\ \\ \mathcal{A}_{EFGH}=\dfrac{EH+FG}{2}\cdotEF=\dfrac{1+2}{2}\cdot1=\dfrac{3}{2}=1,5m^2\\ \\ \\ \mathcal{A}_{BCDPGHE}=6-(1+1,5)=6-2,5=3,5m^2$
