Question

Find the area of parallelogram formed by vector A is equals to 3 ICAP + 2 J cap, b is equals to -3 ICAP +7 jcap

Answer 1

Explanation:

Vectors........ =___________=

Area of parallelogram = A×B

A×B =

| i j k |

| 3 2 0 |

| -3 7 0 |

=

i(0) -j ( 0) + k[(21-(-6)]

=

27 k cap

27 k cap So it will lie on z -axis
