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
