What is the scaling factor used between the two farms?
Scaling factor = Dimension of new farmDimension of old farm
Length of new farm = 150 yd
Length of old farm = 30 yd
Ratio of length = 150 yd30 yd =5
Width of new farm = 75 yd
Width of old farm = 15 yd
Ratio of breadth = 75 yd15 yd =5
∴ Scaling factor = 51 =5
Hence, the scaling factor used is 5.
