17. The area of a triangle ABC can be calculated by AB AC 2, where гAB and rдc are vec- tors connecting the vertices A and B, and A and C, respectively. Determine the area of the triangle shown in the figure. Use the follow- ing steps in a script file to calculate the area. First, define the vectors гOA OB and roc from knowing the coordinates of points A, B, and C. Then determine the vectors AB and TOA roc C (-5,-2,11) TAC TOB A (8,5,-4) B (-7,9,6) TAB FAC from roA, FOB, and roc. Finally, determine the area by using MATLAB's built-in functions cross, sum, and sqrt.
