The figure above shows the plan for the ground floor of a house. The thickness of the walls should be ignored in answering the questions. The dimensions are in feet, and each region is rectangular.
If the hall is\(6 \frac{1}{2}\) feet long, what is perimeter, in feet, of the porcharea?
A. 18
B. 19
C. 20
D. 21
E. 22
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
\(= 2 (5 + 5\frac{1}{2})\)
\(= 21\)
