Question Statement:

In a right-angled triangle ABC with right angle at B, AB = 6 cm and BC = 8 cm. The length of the altitude BD drawn to hypotenuse AC is:

Options:

  • (A) 4.8 cm
  • (B) 5.0 cm
  • (C) 4.5 cm
  • (D) 5.2 cm

Answer Key:

A

Step-by-Step Solution & Explanation

$AC = \sqrt{6^2 + 8^2} = 10$ cm. Area $= (1/2) \times 6 \times 8 = 24$. Also Area $= (1/2) \times 10 \times BD \implies BD = 48 / 10 = 4.8$ cm.
