The area of a triangle ABC can be calculated by |rAB × rAC/2, where rAB and rAC are vectors connecting the vertices A and B and A and C, respectively. Determine the area of the triangle shown in the figure. Use the following steps in a script file to calculate the area. First, define the vectors rOA , rOB and rOC from knowing the coordinates of points A, B, and C. Then determine the vectors rAB and rAC from rOA, rOB and rOC. Finally, determine the area by using MATLAB's built-in functions cross, sum. and sqrt.
