Kelso created the scale drawing below what is the scale factor of his drawing 1 inch equals 8 feet the rectangle is 4 feet by 12 feet
1in : 8ft = 1in : 96in = 1:96
To find the scale factor of Kelso's drawing, we need to compare the dimensions of the actual rectangle to the dimensions in the scale drawing.
In the scale drawing, Kelso states that 1 inch equals 8 feet. Let's analyze that statement. It means that each inch on the scale drawing represents 8 feet in reality.
The dimensions of the actual rectangle are given as 4 feet by 12 feet. So, we need to convert these dimensions to inches.
To convert feet to inches, we know that 1 foot is equal to 12 inches. Therefore, the actual dimensions in inches would be 4 feet x 12 inches/foot = 48 inches (width) and 12 feet x 12 inches/foot = 144 inches (length).
Now, let's compare these dimensions to the scale drawing. We divide each dimension in inches by the corresponding dimension in inches on the scale drawing.
For the width, we have 48 inches (actual) / 1 inch (scale drawing) = 48.
For the length, we have 144 inches (actual) / 1 inch (scale drawing) = 144.
The scale factor is the ratio between the dimensions of the actual object and the scale drawing. In this case, the scale factor is 48:1 for the width and 144:1 for the length.
So, the scale factor of Kelso's drawing is 48:1 for the width and 144:1 for the length.
