Answer:
[tex]34.5^2[/tex]
Step-by-step explanation:
First figure out the rectangular part 3 x 8 = 24
Next find out the triangular part. Since we know that one half of the triangular part is 3 by 4, and a triangle is half a rectangle, we can figure out that 3 x 4 = 12 and 12/2 = 6, and do the same for the 3 x 3 triangle 3 x 3 =9 and 9/2 = 4.5
Now just add it all together: 24 + 6 + 4.5 = 34.5
