 |AD|=(3i-1j)-(-3i-0j)=3i-1j+3i+0j=6i-1j
|BA|=(-3i-0j)-(-1i+3j)=-3i-0j+1i-3j=-2i-3j

Area =|AD|x|BA|
=   i   j    k
    6  -1  0
   -2 -3   0

= -1  0     i        -        6  0    j      +   6 -1   k      
   -3  0                      -2  0               -2 -3           

= 0 i  -   0 j     + (-18-2)k    =   -20 k

√(-20)² =20
