Answer 1

Answer:

78 ?????  I can't find a logic or math error take the answer for what is worth

Step-by-step explanation:

Check my work for yourself and post your answer.

Extend the long diagonal to the point (6,4) to create a large triangle that has a base of 14 and a height 12 so this super triangle area is

      area = 1/2 bh

               = 1/2 (14)(12)

               =  7(12)

               =  84 sq units

Now subtract off two smaller triangles that were created when the diagonal was extended to the (6, 4) point

      area1 = 1/2 bh

                = 1/2 (4)(2)

                =  4 sq units

      area2 = 1/2 bh

                = 1/2 (2)(2)

                =  2 sq units

Total area = area - area1 - area2

                 = 84 - 4 - 2

                 = 78 sq units
