Prove that the area of the parallelogram with diagonal `veca` and `vecb` is `(1)/(2)|vecaxxvecb|`

Show that the area of the parallelogram with diagonals veca and vecb , is 1/2|vecaxxvecb| .

Show that the area of a parallelogram with diagonals veca and vecb is 1/2|veca xx vecb|

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 area of the parallelogram whose diagonals are given by veca and vecb is |vecaxxvecb|/2 Also, find the area of the parallelogram whose diagonals are 2i -j+k and i +3j - k.

Let veca,vecb and vecc be three non zero vectors. The area of the parallelogram formed by veca and vecb as diagonals is veca=hati-2hatj vecb=2hati+hatj+3hatk

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

Given two vectors veca= -hati +hatj + 2hatk and vecb =- hati - 2 hatj -hatk Find a. vecaxxvecb then use this to find the area of the triangle. b. The area of the parallelogram c. The area of a paralleogram whose diagonals are 2 veca and 4vecb

One of the diagonals of parallelogram ABCD with veca and vecb as adjacent sides is veca+vecb . The other diagonal vec(BD) is
