Find the scale factor in each of the following and state the type of size transformation:
Image length = 8cm, Actual length = 20cm.
उत्तर
Image length = 8cm, Actual length = 20cm.
Scale factor = `"Image length"/"Actual length" = (8)/(20)`
Scale factor = 0.4
Since the scale factor < 1 and > 0
⇒ Type of size transformation = reduction.
