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

Find the area of the parallelogram whose diagonals are veca=hati+2hatj+3hatk and vecb=-3hati-hatj+hatk

Find the area of the parallelogram whose diagonals are vectors 3hati+hatj-2hatk and hati-3hatj+4hatk .

Find the area of the parallelogram whose diagonals are : veca=hati+2hatj+3hatk and vecb=-3hati-2hatj+hatk

Find the area of the parallelogram whose diagonals are : veca=hati-2hatj+3hatk and vecb=3hati+2hatj+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
