I NEED HELP PLEASE, THANKS! :)

As you know, a parallelogram's area is calculated by multiplying the length of it's sides, so all we are being asked to do is find the product of u and v -

You would apply cross products in order to determine u * v. Doing so, you would get a solution of -46i + 14j - 58k.

Now we can take the magnitude of  this vector -

u * v = √( - 46 )^2 + ( 14 )^2 - ( 58 )^2,

u * v = ( About ) 75.3 square units,

Solution = Option A

x=67
