Answer:
42 square meters
Step-by-step explanation:
rectangle: 3 x 6= 18 square meters
square: 4 x 5= 20 square meters
triangle: 4 x 2 x 1/2= 4 square meters
18 + 20 + 4= 42 square meters
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
