Here;

The length of the porcharea = \(19 \frac{1}{2}\) - Length of the Hall - Length of the Kitchen

= \(6 \frac{1}{2}- 6 \frac{1}{2}- 8\)

\(= 5\)

Now the breadth of the poarcharea = \(19 \frac{1}{2} - 14\) \(= 5\frac{1}{2}\)

Now the perimeter of the poarcharea = 2(Length + breadth) ; since it is a rectangle

\(= 2 (5 + 5\frac{1}{2})\)

\(= 21\)
