Answer:  
 
Step-by-step explanation:
We know that , the equation of a line that passes through (a,b) and (c,d) is given by :_

Standard form of equation of line = 
Given points =  (7, -3) and (4, -8)
Then, the equation of a line that passes through the points . (7, -3) and (4, -8) is given by -

 [∵ (-)(-)=(+)]
   [∵ (-)(-)=(+)]
 
 
 
 
 
 
 
 
 
 
 
 
Or  
 
Hence, the required equation :-

Hello ^w^
I believe the answer you are looking for is A
I found this answer by adding up the lengths of all the sides.
S -> T = 8
S -> R = 7
Q -> R = 6
P -> Q = 6
P -> T = 10
10 + 6 + 6 + 7 + 8 ->  37
A -> 37
If I am incorrect, please inform me.
Have a good day!
