Vector area of a triangle
- Point A has position vector 8i+13j-2k
- Point B has position vector 10i+14j-4k
- Point C has position vector 9i+9j+6k
- The line l passes through the points A and B
- The point X lies on l, where CX is the shortest distance between C and l
- Find the area of the triangle CXB, giving your answer to 3 significant figures. (Bonus points for an exact answer.)
