The scale factor of Alana's drawing is 3: 72.
You must specify the extent of the shape's enlargement when describing one.
The scale factor is the ratio of two dimensions such that one figure is large and another is small.
The scale factor is done due to the unpractical measurement of any figure.
Dimension in real = 6 feet
Since,
1 feet = 12 inches
6 feet = 72 inches
Dimension in drawing = 3 inches.
Scale factor = Dimension in drawing / Dimension in real
Scale factor = 3/72
Hence "The scale factor of Alana's drawing is 3: 72".
