Since the given coordinates are already in order,
then and two consecutive distances between the coordinates will give length and breadth,
Using distance formula,
(we'll not consider the negative value since distances can't be negative)
Applying this again on 2nd and 3rd coordinates,
(we'll not consider the negative value since distances can't be negative)
Since length's always gotta be greater than bredth
therefore,
the difference will be 5-4= 1 units
Hence width is 1 unit shorter than length.
Note: Unit used is "unit/s"

Complete Question
Suppose there was a cancer diagnostic test was 95% accurate both on those that do and 90% on those do not have the disease. If 0.4% of the population have cancer, compute the probability that a particular individual has cancer, given that the test indicates he or she has cancer.
Answer:
The probability is
Step-by-step explanation:
From the question we are told that
The probability that the test was accurate given that the person has cancer is
The probability that the test was accurate given that the person do not have cancer is
The probability that a person has cancer is
Generally the probability that a person do not have cancer is
=>
=>
Generally the probability that a particular individual has cancer, given that the test indicates he or she has cancer is according to Bayes's theorem evaluated as
=>
