The area of a parallelogram having u and v asedgesis given by .

Further, the two diagonals are u+ v and u- v where u is longer than v. If B= u+ v and A= u- v, what are u and v in terms of A and B?

, of course.also

Find the volume of the parallelepiped whose edges are represented by:

A=2i-3j+4k

B=i+2j-k

C=3i-j=2k
