The first one is 810
The second is -120
Area is length times width so
A = 4.5*3.4 which is 15.3.

Hello!</h2>
The answer is:
1017.88 square feet are blue.
<h2>Why?</h2>
To calculate how many square feet are blue, we need to calculate the area of the bottom of the circular swimming pool.
We need to remember that we can calculate the area of any circle using the following formula:

Now, we know that the diameter of the bottom is equal to 36 feet, so, we can calculate the radius of the bottom using the following formula:

So,

Then, calculating the area we have:

Hence, we have that 1017.88 square feet are blue.
Have a nice day!
