First thing's first... calm down... have some tea or hot cocoa or something. Panicking just sets you up to make mistakes.

2. Ok, you're looking at this as too big of a project. Break it down into smaller parts that you already know. For this, let's carve off the two strips at the top and bottom and figure those out. 93 x 3 is 279 with two strips that gives you 558 ft^2. Next, take off 6 ft from both of the sides, (since you just withdrew the strips at the top and bottom, and there's no point painting twice). That leaves 45 x 6 for each of the side strips, you have two of those, making an area of the sides of 540 ft^2. Now, you haven't given me the length of the middle section on those 18 ft areas. I'll assume that this is a standard basketball court, however, and that the circle in the center is a true circle and the two half circles are the same width. Which means the radius of 6 for that half circle gives me a diameter of 12, (the width of both those rectangles). That means the rectangular painted portions are 12 x 18 x 2 or 432 ft^2. That just leaves you the two half circles and the single circle in the center. If these are the same size, then that leaves 2 x whatever the area of that circle in the center, or (pi x r^2). The radius we already know is 6, and 6 squared is 36.

Now, here's where I have to ask you a question. Because the answer to this question kind of hinges on how many decimal places your math class takes pi out to. Back in my HS days, we just did pi as 3.14. If you've got more places, you'll need to modify my answer.

3.14 x 36 x 2 = 226.08 ft^2 for the two circles. Now, add this to the rest and we get:

226.08 + 558 + 540 + 432 = 1756.08 ft^2.

3. This is just the answer above, subtracted from your total area. 4743 - 1756.08 = 2986.92 ft^2.

4. You need 1756.08 square feet of coverage, there's 400 square feet of coverage in a can of navy blue paint. Since you can't by part of a gallon of paint, you'll need to just go over this amount by less than one can. It's basically 5 cans.

5. Same deal with the maple. My calculator says you'll need 8 of those, rounding up.

6. Entire court, use the big area you found in the beginning. 12 of those.
