Find the scale factor in each of the following and state the type of size transformation:
Model area = 75cm2, Actual area = 3cm2
उत्तर
Model area = 75cm2, Actual area = 3cm2
Actual area
= 3 x 10000cm2
= 30000cm2
Scale factor
= `sqrt(("Model Area")/("Actual Area")`
= `sqrt((75)/(30000)`
= `sqrt((1)/(400)`
= `(1)/(20)`
Scale factor = 0.05
Since the scale factor < 1 and > 0
⇒ Type of size transformation = reduction.
