We must consider the median of the data sets, it may represent the center of the dispersion measure. Then we see answer C is the most suitable one, this is because it's median is approximately to $60.
Length: 1/5 = 2/10
Width: 1/2 = 5/10
Perimeter = 2 (Length + Width)
= 2 (2/10 + 5/10)
= 2 ( 7/10)
= 14/10
= 1 and 4/10 = A. 1 and 2/5
Now the aim of the above discussion is to internalize the mathematical relationships for open-end air columns in order to perform calculations predicting the length of air column required to produce a given natural frequency. And conversely, calculations can be performed to predict the natural frequencies produced by a known length of air column. Each of these calculations requires knowledge of the speed of a wave in air (which is approximately 340 m/s at room temperatures). The graphic below depicts the relationships between the key variables in such calculations. These relationships will be used to assist in the solution to problems involving standing waves in musical instruments.
-2/3x is the slope. the full problem is y=-2/3x + 3
