Two sets A and B are as under: A={(a, b) ∈ R × R:|a-5|<1 and |b-5|<1}; B={(a, b) ∈ R × R: 4(a-6)^2+9(b-5)^2 ≤ 36}. Then:
Two sets A and B are as under :
$$\begin{aligned}
& A=\{(a, b) \in \mathbf{R} \times \mathbf{R}:|a-5|<1 \text { and } \\
& |b-5|<1\} ; \\
& B=\left\{(a, b) \in \mathbf{R} \times \mathbf{R}: 4(a-6)^2+9(b-5)^2\right. \\
& \leq 36\} \text {. Then : }
\end{aligned}
$$
