29.999 sq. feet or 30 sq. feet
Step-by-step explanation:
The thing to remember here is the
- The conversion factor of Inch into feet
- Understanding of scale and model
- Rectangle area
Proceeding with the question
Width of the rectangle=3 inch
Height of the rectangle=4 inch
We know the area (rectangle)= height* width
Area=12 inch
²
We know that scale= sample area/original area
1/30=12/original area of the room
room area= 360 inch
²
Since the final area is needed in sq. feet
We know that 1 inch= 0.08333 feet
Thus 360 inches = 29.999 square feet or 30 square feet (approx.)
