Correct Answer: 65

Solution :

$x^2 + 4y^2 = 17$ and $xy = 2$, where $ x > 0, y > 0$
$⇒ xy = 2$
$⇒4xy = 8$
Now, $(x + 2y)^2= x^2 + 4y^2 + 4xy = 17 + 8 = 25$
$⇒ (x + 2y) = 5$

Correct Answer: $1:(\sqrt2-$1)

Solution :
Area($\triangle$ADE) = Area(trapezium BCED)
⇒ Area($\triangle$ADE) + Area($\triangle$ADE) = Area(trapezium BCED) + Area($\triangle$ADE)
⇒ 2 × Area($\triangle$ADE) = Area($\triangle$ABC)
In $\triangle$ADE and $\triangle$ABC,
$\angle$ADE = $\angle$ABC [i.e., corresponding angles in DE || BC]
$\angle$A = $\angle$A [common angle]
⇒ $\triangle$ADE ~ $\triangle$ABC
⇒ $\frac{\text{Area($\triangle$ADE)}}{\text{Area($\triangle$ABC)}}$ =
