Answer:
100.5 ft^2
Step-by-step explanation:
First find the area of the rectangle
A = l*w
A = 12.16 * 6
A =72.96 ft^2
Then find the area of the triangle
A = 1/2 bh
The base is 12 ft - 6ft = 6ft
The height is 9.16 ft
A = 1/2 ( 9.16) * 6
A = 27.48 ft^2
Add them together
27.48+72.96
100.44 ft^2
Round to the nearest tenth
100.5 ft^2
The mixed number is 4 5/12.
For anyone else who needs the right answer...it’s “parallel to the base”. I just did it and I got it right.
The inverse operation would be 3x34=102
Remark
If you just want the way this would be written out the answer is

Note
1. The quotient is the answer of a division problem.
2. The number is represented by the letter x
