Find the area of the parallelogram having diagonals `2hati-hatj+hatk and 3hati+3hatj-hatk`

Show that the asreas of the parallelogram having diagonals 3hati+hatj-2hatk and hati-3hatj+4hatk is 5sqrt(3)

Show that area of the parallelogram whose diagonals are given by veca and vecb is (|veca xx vecb|)/2 . Also, find the area of the parallelogram, whose diagonals are 2hati - hatj + hatk and hati + 3hatj - hatk .

Show that (veca+vecb)xx(veca-vecb)=-2(vecaxxvecb) and use this result to find the area of a parallelogram whose diagonals are hati-2hatj-3hatk and 2hati-3hatj+2hatk

Find the area oif the parallelogram determined A=2hati+hatj-3hatk and B=12hatj-2hatk

The area of the parallelogram whose adjacent sides are hati-3hatj+hatk and hati+hatj+hatk is

find the area of a parallelogram whose diagonals are veca=3hati+hatj-2hatk and vecb=hati-3hatj+4hatk .

Area of a parallelogram, whose diagonals are 3hati+hatj-2hatk and hati-3hatj+4hatk will be :

Area of a parallelogram, whose diagonals are 3hati+hatj-2hatk and hati-3hatj+4hatk will be:
