Calculate the area of triangle ABC with altitude BD, given A (−6, 0), B (0, 0), C (0, 6), and D (−3, 3).

nata0808 [166]

Answer:

18 unit²

Step-by-step explanation:

If BD is altitude then AC is the base.

<u>The length of AC is:</u>

AC = $\sqrt{6^2+6^2} = 6\sqrt{2}$

<u>The length of BD is:</u>

BD = $\sqrt{3^2 + 3^2} = 3\sqrt{2}$

<u>The area is:</u>

A = 1/2bh
A = 1/2 * $6\sqrt{2} *3\sqrt{2}$ = 18 unit²
