(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The vertices of triangle are (2,0,0) ; (0,3,0) ; (0,0,6) . Find the area of triangle.

2. Relevant equations

3. The attempt at a solution

is it right that i put in determinant like

Area of triangle =

0.5 | 2 0 0 |

| 0 3 0 |

| 0 0 6 |

= 0.5 (2* 3 * 6)

= 18 .

but i think this method is wrong ... the answer of this question is 3 sqrt ( 14) .
