Answer:
The original living room dimensions are 11 feet × 24 feet and the area is 264 feet².
Step-by-step explanation:
Given:
The scale drawing of a living room has the dimensions of 5.5cm x 12cm.
If the scale is 1 cm is equal to 2 feet.
Now, to find the dimensions of original living room and the area of the original living room.
As given 1 cm is equal to 2 feet.
So, 1 cm is equivalent to 2 feet.
Now, let the original dimension be ![y\ cm.](https://tex.z-dn.net/?f=y%5C%20cm.)
Now, solving by cross multiplication method:
![\frac{1}{2} =\frac{5.5}{y}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%3D%5Cfrac%7B5.5%7D%7By%7D)
By cross multiplying we get:
![y=11](https://tex.z-dn.net/?f=y%3D11)
Again:
![\frac{1}{2} =\frac{12}{y}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%3D%5Cfrac%7B12%7D%7By%7D)
By cross multiplying we get:
![y=24](https://tex.z-dn.net/?f=y%3D24)
Thus, the original dimensions are 11 feet × 24 feet.
The original dimensions are 11 feet × 24 feet.
Now, the area of original living room:
![Area = 11\times 24\\Area = 264\ feet^2.](https://tex.z-dn.net/?f=Area%20%3D%2011%5Ctimes%2024%5C%5CArea%20%3D%20264%5C%20feet%5E2.)
And the area is 264 feet².
Therefore, the original living room dimensions are 11 feet × 24 feet and the area is 264 feet².
