Question

In the figure $DE\parallel BC$. Find $AD$.

• A. 2.4 cm
• B. 2.6 cm
• C. 3.4 cm
• D. 3.6 cm

Answer 1

The correct option is A 2.4 cm

Given: $DE\parallel BC$

By equal Intercept theorem,

$\frac{AD}{DB}=\frac{AE}{EC}$

$\frac{AD}{7.2}=\frac{1.8}{5.4}$

$\Rightarrow AD=\frac{1.8\times 7.2}{5.4}$

$\therefore AD=2.4$ cm
