Determine the area of the quadrilateral whose vertices are (1,3), (6,5), (9,1) and (3,-3).
HI sharkman ,
THe area would be ,
Gosh , i have a problem typing matrix . sorry if its a bit messy . Generally , if you are asked to find the areas of triangle or quadrilateral given their vertices, you can do that . DO you know how to get its determinant ?

Ok...but I a not familiar with matrices. Is there a way to answer the question using A = h/2(base1 + base2)?
I would need to find base 1, base 2 and the height after graphing the quadrilateral, right?
