Given a point in coordinates form

, one can compute the cartesian form like this:

We have:

We get the cartesian form then:
To find the length, divide the peremiter by 2 and then subtract the width.
Length= Peremiter/2 - width
L = P/2 - W
L = 168/2 - 36
L = 84 - 36
L = 48
The length is 48
Definitely Graph C.
The dots are aligned correctly to the line better than the other graphs.
