What is the area of parallellogram if its diagonals are represented by vectors
p=5i-4j+3k
q=3i+2j-k
take the cross product of the two vectors and divide it by 2 then u get the area of the parallelogram
if the answer is negative then take it as positive because we take the modulus of cross product , and also the area can never be negative
I tried that way. But it didnot come.
note that it is the diagonals, not sides
