3. As shown in Figure 1, in Marla's garden, there are 3 rows and 2 columns of a total of six rectangular flower beds, each 6 feet long and 2 feet wide. There is a 1-foot wide path left between the flower beds and around the perimeter of the garden. What is the area \( S \) of the path in square feet?
(A) 72
(B) 78
(C) 90
(D) 120
(E) 150
3. B.
$$
\begin{aligned}
S= & (1+2+1+2+1+2+1) \times \\
& (1+6+1+6+1)-6 \times 6 \times 2 \\
= & 150-72=78 .
\end{aligned}
