Answer:
6 inches by 4 inches
Step-by-step explanation:
You want the dimensions of the scaled copy of a 12 in by 8 in rectangle copied with a scale factor of 1/2.
Scaled drawing
The size of a scaled drawing is the real-world (actual) size, multiplied by the scale factor of the drawing.
Application
A drawing that has a scale factor of 1/2 will have dimensions that are 1/2 those of the original object.
drawing size = (1/2) · (actual size)
drawing length = (1/2) · (actual length) = 1/2 · 12 in = 6 in
drawing width = (1/2) · (actual width) = 1/2 · 8 in = 4 in
The scale copy is 6 inches long and 4 inches wide.
