Answer 2

Length of CD = 2.4 cm

Step-by-step explanation:

Given data

BC = 4 cm

AC = 3 cm

AB = 5 cm

CD is perpendicular to AB.

We know that for the right angle triangle,

CD × AB = AC × BC  ------ (1)

Put all the value in above equation. we get,

⇒ CD × 5 = 3 × 4

⇒ CD = $\frac{12}{5}$

⇒ CD = 2.4 cm

Thus the length of CD = 2.4 cm
