<h3>Given : </h3>
- Base of triangle = 8 cm
- Height of triangle = 4 cm

<h3>To Find : </h3>

<h3>Solution :</h3>
As, we have :
- Base of triangle, b = 8 cm
- Height of triangle, h = 4 cm

So, to find area of triangle we have a formula :






Hence, area of given triangle is 16 cm².
12
2 multiplied by 6 is 12 and so 1 multiplied by something is 12
Hope this helps.
The vector AB is found by subtracting the coordinates of point B from the coordinates of point A => (8, 3, 4) - (5, 7, - 2)
(8, 3, 4) - (5, 7, - 2) = (3, - 4, 6)
=>
a) a 3 x 1 column =
| 3 |
| -4 |
| 6 |
b) xi + yj + zk
=> 3i - 4j + 6k
