Charlie has a drawing of his bedroom that measures 8 1/2 inches long by 7 1/4 inches wide. If the real room measures 15 ft in length, what is the rooms width?
w/(7 1/4) = 15/(8 1/2)
w = 435/34 = 12 27/34
Strange measurements.
To find the width of the room, we need to convert the measurements from inches to feet.
First, let's convert the length of the drawing from inches to feet:
The length of the drawing is 8 1/2 inches.
We divide 8 1/2 by 12 (the number of inches in a foot) to get 8.5 / 12 = 0.7083 feet.
Now, let's convert the width of the drawing from inches to feet:
The width of the drawing is 7 1/4 inches.
We divide 7 1/4 by 12 to get 7.25 / 12 = 0.6042 feet.
Next, we need to find the scale factor between the drawing and the actual room. We can do this by dividing the length of the real room by the length of the drawing:
The length of the real room is 15 feet.
The scale factor is 15 / 0.7083 = 21.184.
Finally, we can find the width of the real room by multiplying the width of the drawing by the scale factor:
The width of the drawing is 0.6042 feet.
The width of the real room is 0.6042 * 21.184 = 12.8002 feet.
Therefore, the width of the room is approximately 12.8002 feet.
