There is a simpler solution: write down the Pythagoras theorem for the right-angled triangle made by r, r-1, and r-2. See the figure, even though it's not a good one! Interestingly, the equation obtained at the end is the same as the one obtained immediately here!

r^2=(r-1)^2+(r-2)^2 Gives r=5. So Area=25π

Additionally, for r between 2 and 10 r=5 is the only r that gives integer length of red rectangle. Gave this to chatgpt: For this photo r must be 5 because of intersecting cord theorem. But expanding on that. For every circle in a square. The red rectangle should have a definite length and width relative to r of the square. Let’s (1) develop a formula of length and width relative to r. (2) calculate length and width for r between 2 and 10. And got

Dang, I went about this all wrong. Ended up with a quartic for r which turned out to have solutions 1, 5 and ±√5 🤨.

Solución: [(L-2)/2]² = 2(L-2) → (L-2)² = 8(L-2) → L²-4L+4 = 8L-16 → L²-12L+20 = 0 → L = {2, 10} ☝🏻 L > 2 ☝🏻 L = 10 ☝🏻 A(Blue) = πr² ☝🏻 r = L/2 = 5 ☝🏻 A(Blue) = 25π u² ✅ A(Blue) = 78.54 u² ✅
