Let A={(α, β) ∈ R × R:|α-1| ≤ 4 and |β-5| ≤ 6} and B={(α, β) ∈ R × R: 16(α-2)^2+9(β-6)^2 ≤ 144}. Then

Let $\displaystyle A=\{(\alpha, \beta) \in \mathbf{R} \times \mathbf{R}:|\alpha-1| \leqslant 4$ and $\displaystyle |\beta-5| \leqslant 6\}$ and $\displaystyle B=\left\{(\alpha, \beta) \in \mathbf{R} \times \mathbf{R}: 16(\alpha-2)^2+9(\beta-6)^2 \leqslant 144\right\}$. Then
