Please help on geometry - analytic geometry

What is the area, in square units, of a triangle whose vertices are at (4,-1), (10,3) and (4,5) ?
How to do this?
It helps if you plot the points first, then you can find the length of the sides of the triangle.
area of a triangle is
1/2 base times height.
I could also i think find the area of the square/rectangle and minus the pieces that are not part of the triangle
Knights, If you are in analytic geometry, I am pretty certain your teacher expects an analytical approach, not a graphical approach. See the example I posted.
