The side lengths of the scaled copy are 2 feet by 3 feet and to scale the copy back to its original size, the scale factor to use is 3
1. What are the side lengths of the scaled copy? feet by feet
The given parameters are:
Length = 6 feet
Width = 9 feet
The scale factor is given as:
k = 1/3
So, the side lengths of the scaled copy are
Length = 1/3 * 6 feet = 2 feet
Width = 1/3 * 9 feet = 3 feet
Hence, the side lengths of the scaled copy are 2 feet by 3 feet
2. Suppose you want to scale the copy back to its original size. What scale factor should you use?
In (1), we have:
The scale factor is given as:
k = 1/3
To scale the copy back to its original size, the scale factor to use is:
Scale = 1/(1/3)
Evaluate
Scale = 3
Hence, to scale the copy back to its original size, the scale factor to use is 3
