Yikes. I'm a fellow millennial, and math is my kryptonite, but even I can see how it's solved. It would take me all day and half the night, but I would get it done eventually. I'm kind of relieved we had the dummy-level math when I was in school though!
Uh oh, now that I'm called out, I shouldn't have been so sassy. I believe you start with the area of the whole rectangle, then calculate the area of the two cut-out circles, using the radius given. Subtract 1/4 of the area of both those circles from the area of the rectangle. Then you move to the rounded edges, which I had to really think about, but I believe you start by calculating the area of both the circles using the radius again (it's a bit blurry, but I assume that's what those numbers are). Then I think you mentally pretend each of those circles are in a square, so calculate the area of the "square", subtract the area of the circle from the area of its "square", you should be left with just the edge corners. Subtract 1/4 of that amount from the rectangle, and that should give you the rounded corner. Was I close?

OK what's the answer?

Nope. Spot on.
