Option 1: $1:\sqrt2$
Option 2: $1:2$
Option 3: $\left ( \sqrt2-1 \right ):\sqrt2$
Option 4: $\sqrt2:1$
Correct Answer: $\left ( \sqrt2-1 \right ):\sqrt2$
Solution : Given, area of ($\triangle ADE)$ = area of $BDEC$ ⇒ $\triangle 2ADE = \triangle ABC$ Since, $DE \parallel BC$ ∴ $\triangle ADE$ ~ $\triangle ABC$ Now, $\frac{area (\triangle ADE)}{area (\triangle ABC)} = \frac{1}{2} = \frac{AD^2}{AB^2}$ ⇒ $\frac{AB}{AD} = \sqrt2$....................(1) ⇒ $\frac{AB}{AD}-1
