Find the area of the following shape. You must show all work to receive credit. (10 points)

Figure ABCDEF is shown. A is located at negative 5, negative 8. B is located at 1, negative 8. C is located at 3, negative 5. D

The key to solving this problem is drawing a rectangle outside the figure and subtracting the areas of the triangles formed from the are of the rectangle. so first, find the area of the rectangle, the length is 11 and the width is 5 so the area is 55. next, find the area of the triangles. Triangle 1 has sides of 4 and 3 so the area is 6. Triangle 2 has sides of 5 and 5 so the area is 25/2. Triangle 3 has sides of 2 and 5 so the area is 5. then, add the area of the triangles up to get 47/2. finally, subtract 47/2 from 55 to get the area of the figure which is 63/2.

I thought I knew but I was wrong. Sorry!
