Find the scale factor in each of the following and state the type of size transformation:
Image length = 6cm, Actual length = 4cm.
उत्तर
Image length = 6cm, Actual length = 4cm
Scale factor = `"Image length"/"Actual length" = (6)/(4)`
Scale factor = 1.5
Since the scale factor > 1
⇒ Type of size transformation = enlargement.
