I believe a=9
You divide a by 0.9 to get the variable alone. Then you divide 8.1 by 0.9 as well. What you do to the one side u must do to the other side. Therefore you should get A=9

Answer: 47.5 ft^2
Step-by-step explanation: First find the area of the rectangle using the formula length*height. This is 10*4 or 40.
Then find the area of the bottom triangle using the formula (base*height)/2. This will be (3*3)/2, which simplifies to 9/2, which is 4.5.
Then find the area of the top triangle using the same formula, which will be (2*3)/2, which simplifies to 6/2, which is 3.
Add all of these together. 40+3+4.5=47.5.
