Hi i am using this code to calculate areas for multy triangles and rectangles. I need a change to this code. I want to replace the talbe with analicic calculation mtext like this :

E1 = 1/2 x 59.32 x 102.36 = 3035.99 sq.m
E2 = 1/2 x 16.67 x 85.95 = 716.39 sq.m
E3 = 73.39 x 97.33 = 7143.04 sq.m
Total = 3035.99 + 716.39 + 7143.04 = 10895.42 sq.m

and insert the calculation texts in layout with txt size 2.5
