A. 18

B. 19

C. 20

D. 21

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

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

$$= 21$$
